查询词典 salt acid

However, the quality of the copper film deposited by this method is poor. In order to resolve this problem, we study the influence of some additives on two different kinds of electroless copper plating which using sodium hypophosphite as reducing agent and sodium citrate as chelating agent, sodium citrate and ethylene diamine tetraacetic acid disodium salt (EDTA·2Na). Electrochemical methods were used to test the anodic and cathodal polarization processes which can explain the mechanism of the influence of additives.
