离子交换树脂简介 

      离子交换树脂是一类具有离子交换功能的高分子材料。在溶液中它能将本身的离子与溶液中的同号离子进行交换。按交换基团性质的不同，离子交换树脂可分为阳离子交换树脂和阴离子交换树脂两类。常用的离子交换设备装填的树脂大都是201ｘ7强碱性 系阴离子交换树脂及001ｘ7强酸性 系阳离子交换树脂。如果在水质要求特别高的场合则使用抛光树脂。一般情况下，常规的钠离子交换树脂带有大量的钠离子。当水中的钙镁离子含量高时，离子交换树脂可以释放出钠离子，功能基团与钙镁离子结合，这样水中的钙镁离子含量降低，水的硬度下降。硬水就变为软水，这是软化水设备的工作过程。
      当树脂上的大量功能基团与钙镁离子结合后，树脂的软化能力下降，可以用氯化钠溶液流过树脂，此时溶液中的钠离子含量高，功能基团会释放出钙镁离子而与钠离子结合，这样树脂就恢复了交换能力，这个过程叫作“再生”。

离子交换树脂参考指标
       1、PH范围：1-14
       2、较高使用温度：氢氧型≤40℃ 氯型≤80℃
       3、转型膨胀率：（Cl→OH）18-22%
       4、工业用树脂层高度：1.5m以上
       5、再生液浓度：NaOH:3-5%
       6、再生液用量：体积：树脂体积=3-5：1
       7、再生液流速： 4-6 m/h
       8、再生接触时间：45-60 min 
       9、正洗流速： 15-25 m/h
     10、正洗时间： 30 min
     11、运行流速： 15-25 m/h
     12、工作交换容量：≥400mol/m3

离子交换树脂用途
      1、水处理：水处理领域离子交换树脂的需求量很大，约占离子交换树脂产量的90%，用于水中的各种阴阳离子的去除。目前，离子交换树脂的较大消耗量是用在火力发电厂的纯水处理上，其次是原子能、半导体、电子工业等。

      2、食品工业：离子交换树脂可用于制糖、味精、酒的精制、生物制品等工业装置上。例如：高果糖浆的制造是由玉米中萃出淀粉后，再经水解反应，产生葡萄糖与果糖，而后经离子交换处理，可以生成高果糖浆。离子交换树脂在食品工业中的消耗量仅次于水处理。

      3、制药行业：制药工业离子交换树脂对发展新一代的抗菌素及对原有抗菌素的质量改良具有重要作用。链霉素的开发成功即是突出的例子。近年还在中药提成等方面有所研究。

      4、合成化学和石油化学工业：在有机合成中常用酸和碱作催化剂进行酯化、水解、酯交换、水合等反应。用离子交换树脂代替无机酸、碱，同样可进行上述反应，且优点更多。如树脂可反复使用，产品容易分离，反应器不会被腐蚀，不污染环境，反应容易控制等。
（ ）的制备，就是用大孔型离子交换树脂作催化剂，由异丁烯与 反应而成，代替了原有的可对环境造成严重污染的 。

      5、环境保护：离子交换树脂已应用在许多非常受关注的环境保护问题上。目前，许多水溶液或非水溶液中含有有毒离子或非离子物质，这些可用树脂进行回收使用。如去除电镀废液中的金属离子，回收电影制片废液里的有用物质等。

      6、湿法冶金及其它：离子交换树脂可以从贫矿里分离、浓缩、提纯及提取稀土元素和贵金属。

树脂预处理

      １、阳树脂的预处理
      首先，使用饱和食盐水，取其量约等于被处理树脂体积的两倍，将树脂置于食盐溶液中浸泡18-20小时，然后放尽食盐水，用清水漂洗净，使排出水不带黄色；
      其次，再用2%-4%NaOH溶液，其量与上相同，在其中浸泡2-4小时（或小流量清洗），放尽碱液后，冲洗树脂直至排出水接近中性为止；
      较后，用5%HCL溶液，其量亦与上述相同，浸泡4-8小时，放尽酸液，用清水漂流至中性待用。

      ２、阴树脂的预处理
      其预处理方法中的 步与阳树脂预处理方法中的 步相同；而后用5%HCL浸泡4-8小时，然后放尽酸液，用水清洗至中性；而后用2%-4% NaOH溶液浸泡4-8小时后，放尽碱液，用清水洗至中性待用。

保存方法

      离子交换树脂不能露天存放，存放处的温度为0-40℃，当存放处温度稍低于0℃时，应向包装袋内加入澄清的饱和食盐水、浸泡树脂。此外，当存放处温度过高时，不但使树脂易于脱水，还会加速阴树脂的降解。一旦树脂失水，使用时不能直接加水，可用澄清的饱和食盐水浸泡，然后再逐步加水稀释，洗去盐分，贮存期间应使其保持湿润。

Introduction to ion exchange resin

Ion exchange resin is a kind of polymer material with ion exchange functions.It can itself in aqueous solution of ion exchange with the number with ions in solution.According to the properties of exchange group, ion exchange resin can be divided into two categories, cation exchange resin and anion exchange resin.Commonly used ion exchange equipment filling resin is mostly 201 x7 strongly basic anion exchange resin and styrene 001 x7 strongly acidic styrene type cation exchange resin.If the water quality requirements polishing resin are used the occasion of particularly high.In general, the conventional sodium ion exchange resin with large amounts of sodium ions.When the high content of calcium and magnesium ions in the water, can release sodium ion exchange resin, functional groups combined with calcium and magnesium ions, so that the content of calcium and magnesium ions in the water is reduced, the hardness of water drops.Hard water becomes soft water, this is the working process of the demineralized water equipment.
When a large number of functional groups on the resin combined with calcium and magnesium ions, the resin softening ability, can use sodium chloride solution through the resin, a high content of sodium ion in the solution, functional groups can release calcium and magnesium ions with sodium ions, was back this resin exchange capacity, this process is called "renewable".
Ion exchange resin
1, PH range: 1-14
Type 2, highest use temperature: hydrogen chlorine type 40 ℃ 80 ℃ or less or less
3, transformation rate (Cl - > OH) 18-22%
4, industrial resin layer height: 1.5 m above
5, renewable liquid concentration: NaOH: 3-5%
6, the dosage of renewable liquid: volume: resin size = 3-5 to 1
7, regeneration fluid velocity: 4 to 6 m/h
8, regeneration contact time: 45 to 60 min
9, is wash velocity: 15-25 m/h
10, is washing time: 30 min
11, operating velocity: 15-25 m/h
12, working exchange capacity: p 400 mol/m3
Ion exchange resin
1, water treatment, water treatment of ion exchange resin in the field of high demand, accounting for about 90% of production, ion exchange resin for the water removal of various kinds of ion of Yin and Yang.At present, the largest consumption of ion exchange resin is used in water treatment of coal-fired power plants, followed by the atomic energy, semiconductor and electronic industry, etc.
2, the food industry: ion exchange resin can be used for the refined sugar, monosodium glutamate, wine, biological products and other industrial device.For example, production of high fructose syrup is after extraction of starch from corn, then through hydrolysis reaction, glucose and fructose, and then treated by ion exchange, can produce high fructose syrup.Ion exchange resin consumption is second only to water treatment in food industry.
3, the pharmaceutical industry, pharmaceutical industry ion exchange resin to the development of a new generation of antibiotics and to improve the quality of original antimicrobial plays an important role.Successful development is outstanding example of streptomycin.In recent years also study in traditional Chinese medicine (TCM) commission, etc.
4, synthetic chemistry and petroleum chemical industry: in acid and alkali is commonly used in organic synthesis as a catalyst for the esterification, hydrolysis, ester exchange, hydration reaction.With ion exchange resin instead of inorganic acid, alkali, can be the same reaction, and the advantages of more.Such as resin can be used repeatedly, easy separation of products, the reactor will not be corrosion, polluting the environment, reaction is easy to control, etc.
The preparation of methyl tert-butyl ether ( ), is using macroreticular ion exchange resin as catalyst, the reaction of isobutylene and methanol, and replaces the original can cause serious pollution to the environment of tetraethyl lead.
5, environmental protection: ion exchange resins have been used in many very concern environmental protection issues.At present, many aqueous or non-aqueous solution containing toxic ions or non-ionic substances, these can be used to recycle and use resin.If remove the metal ion in the electroplating effluent, recycling filmmaking useful substances in the waste liquor, etc.
6, hydrometallurgy and other: ion exchange resin from separation, enrichment and purification of depleted uranium in uranium and rare-earth elements and precious metal extraction.
Resin pretreatment
1, Yang resin pretreatment
First, the use of saturated salt water, take its quantity is approximately equal to the treated two times the size of resin, the resin at 18 to 20 hours soaked in salt solution, and then put salt water, rinse clean, make the discharge water without yellow;
Second, with 2% 4% NaOH solution, its quantity and the same, soaking in 2-4 hours (or small flow cleaning), is put after the lye, flushing resin until discharge water close to neutral.
Finally, with 5% HCL solution, the amount is the same, for four to eight hours, put acid, with water to neutral.
2, Yin resin pretreatment:
The first step in the pretreatment method and Yang resin pretreatment method is the first step in the same;And then use 5% HCL immersion 4 to 8 hours, and then put acid, water washing to neutral;And then soaked in 2% 4% NaOH solution 4 to 8 hours, put all lye, use clean water to neutral.
Save method
Ion exchange resin in the open air, not the temperature of the place of 0 to 40 ℃, when the deposition temperature slightly lower than 0 ℃, should clarify added to a saturated salt water into the bags, soak resin.In addition, when the temperature of the place is too high, not only make the resin is easy to dehydration, can also accelerate the degradation of Yin resin.Once the resin filtration, not directly add water when using, can be used to clarify the saturated salt water soak, and then gradually add water dilute, wash salt, should keep it moist during storage.
