硼特效树脂离子交换法分离硼的研究

The Investigation of Ion Exchange Technique For Extracting Boron From Aqueous Fluids by Boron Specific Ion Exchange Resin

本文对AmberliteIRA743硼特效树脂交换分离础的特性及其影响因素进行了研究.它适用于各种地质作品中硼的分离提取，特别是在硼同位素地球化学研究时。必须进行础纯化的场合。

The ion exchange characteristics of Amberlite IRA 743 resin for boron has been studied indetail in this study. The results show that Amberlite IRA 743 resin, a boron - specfic ionexchange resin, can quantitatively extract boron as B(OH)4 - form from week basic solution. Theboron in natural aqueous fluids with low pH also is extracted by Amberlite IRA 743 resin if Cl-and SO anions are present in natural aquous flulds due to adsorption of Cl- and S0,resulting in increase of pH of sample solution in the column. However the volume of samplesolution being exchanged should be restricted. The volume of sample solution being exchanged isdecreased with decrease of pH in sample solution.
