摘要
介绍了以镍板为阳极,不锈钢为阴极恒电位电解法去除HF中微量水分的方法.用卡尔—费休法对处理后的HF的含水量进行测定,结果表明,随着电解时间的延长,电解电流和氟化氢中的水分含量逐渐减小,最后达到一定值.
The method with a falcial anode, stainless steel cathode and constant pressure to get rid of little water in HF is introduced. The worked HF was measured with Karl-Fischer titration method. The results showed that when the state of anode is constant, the current water content of worked HF decrease with the electrolysis and reach the last content.
