This standard compared with GB/T 8144-1987 standard, the main changes are as follows. --- Increasing the exchange capacity determination of sodium cation exchange resin. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee plastic universal methods and products Club (SAC/TC15/SC4) centralized. This standard is mainly drafted by. Xi'an Thermal Power Research Institute Co., Ltd., Jiangsu Su Qing water treatment engineering company, Zhejiang Industrial glory for shares Parts Limited, East Zibo Chemical Co., Ltd., the national quality inspection center of a synthetic resin. The main drafters of this standard. Wang Guang Zhu, Qian Ping, Cai Xiaohua, Shen Jianhua, Cuihuan Fang, Di Jinghua, Wang Jiandong. This standard replaces the standards previously issued as follows. --- GB/T 8144-1987. Exchange capacity of the cation exchange resin Determination1 ScopeThis standard specifies the styrene strong acid and sodium hydrogen type cation exchange resin, an acrylic weakly acidic cation exchange resin cross Determination of exchange capacity. This standard applies to styrene strong acid and sodium hydrogen type cation exchange resin, an acrylic weakly acidic cation exchange resin exchange Determination of capacity.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms.

The RH --- represents a cation exchange resin (hydrogen form), which functional group may be a sulfonic acid group and/or carboxyl and phenolic groups; RNa --- represents a cation exchange resin (sodium form). When hydrogen type cation exchange resin is soaked in a solution of calcium chloride, only the strong acid groups (sulfonic acid group) can react, the replacement of titration To hydrogen ions (H +), strong acid cation exchange resin computing group exchange capacity. Their reaction is. 2RH + CaCl → 2 R2Ca + 2HCl In total exchange capacity of the cation exchange resin with a strong acid group exchange capacity of the difference between the calculated exchange capacity of weak acid groups. Method 3.2 Determination of sodium cation exchange resin exchange capacity Summary Sodium cation exchange resin under the dynamic by excess 1mol/LHCl regeneration solution, and then water to wash away the excess amount of HCl solution Liquid resin into the hydrogen form. Under the dynamic by excess 1mol/LNaCl solution, exchange group is substituted with hydrogen ions to sodium ions dissolved Solution, the reaction is as follows. → RH + NaCl RNa + HCl All effluent was collected, the hydrogen amount was measured for calculating ion exchange capacity of the whole resin.4 Instrument4.1 Glass-exchange column. see GB/T 5760. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 8144-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 8144-2008_English as soon as possible, and keep you informed of the progress.
