摘　　要：本文在醋酸镁介质中，盐酸溶液形成缓冲溶液后，采用Ｌｉ＋离子选择性膜电极研究了ｐＨ值、ＭｇＣｌ２、ＮａＣｌ和ＫＣｌ对电极响应的影响，得到良好的效果．本法可应用于含ＭＳＣｌ２、ＮａＣｌ和ＫＣｌ的盐酸水溶液体系中锂离子浓度的测定．In this paper, when the hydrochloride acid in medium of Mg (Ac) 2, was formed into a buffer solution. The effects of pH values, MgCl2, NaCl and KCl to the Li electrode respone by a Li ionicelective membranous-electrode have been studied. The method can be used to determine the concentration of Lithium in the systems of MgCl2-HCl-H2O, NaCl-HCl-H2O and KCl-HCl-H2O.
