Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Plastics Standardization Technical Committee General Method and Product Subcommittee (SAC/TC15/SC4). This standard is mainly drafted by. Jiangsu Suqing Water Treatment Engineering Group Co., Ltd., Xi'an Thermal Power Research Institute Co., Ltd., Zhonglan Chenguanghua Industrial Research and Design Institute Co., Ltd., Zibo Dongda Chemical Co., Ltd., Dandong Mingzhu Special Resin Co., Ltd., Anhui Jidong Chemical Co., Ltd. Company, Shandong Daun Polymer Materials Co., Ltd. The main drafters of this standard. Peng Zhanghua, Qian Ping, Wang Guangzhu, Wang Yonggui, Qi Jinghua, Peng Huimin, Yao Nengping, Ding Jinqing, Zhao Lei, Luo Xiaoxia. Method for determining regeneration conversion rate of cation exchange resin Caution - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions. question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set by the relevant national regulations.

1 Scope

This standard specifies the method for determining the regeneration conversion rate of hydrogen-type strongly acidic cation exchange resins. This standard applies to the determination of the regeneration rate of hydrogen-type strong acid cation exchange resin.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. Preparation of GB/T 601 chemical reagent standard titration solution Preparation of preparations and products used in GB/T 603 chemical reagent test method GB/T 5475 ion exchange resin sampling method GB/T 5476 ion exchange resin pretreatment method GB/T 5757 ion exchange resin water content determination method GB/T 6682 Analytical laboratory water specifications and test methods

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Regeneration rate percentageregeneration The degree of regeneration of the cation exchange resin under the regenerative type (hydrogen type), usually the hydrogen exchange capacity of the original cation exchange resin It is expressed as a percentage of the hydrogen exchange capacity of the cation exchange resin after thorough transformation and regeneration.

4 Principle

When the regenerated form (hydrogen type) strongly acidic cation exchange resin reacts with an excess of a salt (such as sodium chloride) solution, the exchanged H and When a monobasic strong base (such as sodium hydroxide) solution is reacted, the hydrogen exchange capacity of the cation exchange resin can be calculated according to the titration amount, and the reverse The formula should be. RH NaCl → RNa HCl HCl NaOH → NaCl H2O In the formula. RH --- indicates a cation exchange resin (hydrogen type); RNa --- represents a cation exchange resin (sodium type). According to this, the hydrogen exchange capacity of the cation exchange resin which was originally and completely converted to the regenerated form can be calculated. ......
