电解法制备次磷酸钴

Electrodialytic production of cobalt hypophosphite

研究了以金属钴和次磷酸钠为原料,采用六室电渗析槽电解法制备次磷酸钴的方法.通过实验确定了最佳工艺条件.这种方法制备的次磷酸钴产品纯度高,工艺简单,操作方便,适合大规模生产,同时无废渣、废液产生,属清洁生产.

A method for producing cobalt hypophosphite by contacting cobalt anode with a solution of hypophosphite anions and applying direct current through anode to cathode is introduced in this paper. A six-compartment electrodialysis cell embodying the method is described. The optimal conditions and relative technologies of producing cobalt hypophosphite are discussed during the process. There is neither solid waste residue nor discarded solution, so this method is environment friendly.
