摘要
利用糖精钠与盐酸反应生成不溶于水而溶于乙酸乙酯的物质,将其萃取出来,然后再利用氢氧化钠对其进行滴定分析,采用二分试差法准确测定了某镀光亮镍添加剂中糖精钠及某镀光亮镍液中糖精钠的含量,分别为88.38,0.945 0 g/L,相对平均偏差分别为0.08%,0.3%。
When hydrochloric acid was added into saccharin sodium solution, chemical reaction happened, whose product was glucide, which cannot be dissolved in water, however, it can be dissolved by ethyl acetate, therefore glucide can be extracted from other components, then can be determined by titration with sodium hydroxide. Besides dichotomy, trial and error methods were used to determine the content of saccharin sodium in the additives of bright nickel plating and electroplating solution. The results are 88.38 and 0. 945 0 g/L, respectively. The relative average deviations are 0.08% and 0.3 %, respectively.
