摘要
用直接测量电解系统析氧量的方法,确定了氯酸盐电化生产过程的电流效率,并考察了溶液的组成(Cl^-、ClO_3^-、HClO及ClO^-)、操作参数(电流密度、电解槽和反应器温度、溶液的酸碱度及电极表面的液流速率)、添加盐及电极性能对电流效率的影响.
A new method of measuring the flow capacity of cell gas in the chlorate cell process equipped with an oxygen cathode is applied to investigate the influence of changes in the concentrations of solutions (chloride, chlorate, hypochlorite and addition of foreign salts) and changes in the operation parameters (current density, temperature, pH and flowvelocity) as well as changes in the anode materials on chlorate current efficiency. The concentrations of salts (chloride and chlorate), current efficiency and energy consumption as a function of time are given in a batch process with sodium chloride from 310 g/L to 30g/L.
