STUDY ON THE SOLUTION CHEMISTRY FACTORS IN THE ELECTROCHEMICAL PREPARATION OF HIGH EFFECTIVE POLYALUMINUM CHLORIDE

In the process of electrochemical preparation of polyaluminum chloride (PAC), some key factors can be controlled on-line,so the high quality liquid PAC with high basicity .B(OH-/A1) and high Alb content can be prepared. This paper studies several important solution chemistry factors, such as the property concentration and composition of electrolyte , pH , ions transformation and species alternation of PAC. From the experimental results,the optimum solution chemistry conditions are determined for preparing high quality PAC with a given basicity . The study also proves that there is a fixed relationship between solution chemistry factors and electrochemical parameters.
