Boron Selective Anion Exchange Resin
选择性除硼螯合树脂
Product Description & Applications/产品简介与应用
ECS980选择性除硼螯合树脂是一种苯乙烯和二乙烯苯交联的,具有N-甲基葡萄糖胺基的大孔结构螯合树脂。这种化学结构在官能团中具有多价醇基部分与硼之间生成络合阴离子,其胺基部分作为阴离子交换基捕捉生成的络合阴离子,从而选择吸附硼离子。这种树脂不受大量共存盐类的影响。同时反应对PH值很敏感,络合离子只有在中性或碱性溶液里才能生成,在酸性溶液里络合离子分解。
用途
制备不含硼的镁盐溶液。12%的氯化镁中一般含100ppm左右的硼,通过树脂处理将硼量减低到10ppm以下以生产出优良的镁。饮用水、灌溉用水等含硼水溶液中硼的去除。海水淡化脱硼,核反应堆硼含量调节.
