摘要
用正交试验确定了苦杏仁酸重量法测锆的最佳条件,提出了以氟化氢钾为熔剂使试样分解与除硅同步进行,从而简化了沉淀分离法除硅的繁琐手续,结果令人满意。
An orthogonal testing has been used to determine the optimum condition for the determination of zirconia by bitter almond acid grarimetric analysis.It has been suggested that potassium hydrogen fluoride be used as solvent to synchronize the decomposition and de-siliconization of the specimen. This method simplifies the determination process and good result has been obtained
