摘要
碘量法测定锗,方法简便,选择性好,精确度较高。本文介绍了对于难溶金属镍基钎焊料中猪测定,采用磷酸介质中次亚磷酸钠将Ge4+还原为Ge2+,以磺酸钾滴定的方法。采用正交试验,选用较优试验条件。
Among the methods determining Ge is Simple,sensible and more accurate iodimetry.Determing Ge in the least soluble metal nickle-base lead solder is presented in this paper that Ge4+ is reduced to Ge2+ by sodium hypophophorous and then titrated by potassium iodate in phosphoric acid medium through the orthogonal test and proper conditions of test. The analysis for Ge has virtues of equipment simplifications, strong suitibility and praedvity.
