摘 要:本文使用微分法精确决定难溶氯化物(CuCl,AgCl,PbCl)的沉淀最佳条件[Cl]T,pClop以及净化最低浓度[Me]min。并对铜歧化反应Cu2++Cu=2Cu+在氯化溶液中平衡作了电化平衡计算,确定了脱氯的极限浓度。
Abstract: The differential calculus method(d[Me]T/dpcl=0)is used to determine the optimumconditions for precipitation of sparely soluble chlorides (such as CuCl, AgCl, PbCl2),[Cl]T and pClcp, and critical low concentration[Me]min. Then, an electrochemicalanalysis is made for disproportional reaction Cu2++Cu=2Cu+ in chloride solution,which makes it possible to determine the critical low concentration of dechlorinationPurification.
