摘要
在大量实验的基础上．建立了在非水条件下快速测定食品中糖精钠的方法，以冰乙酸为溶剂，用高氯酸的冰乙酸标准溶液滴定．RSD在0．92％～2．93％，加标回收率在97．13％～100．3％．实验结果表明，本法定量分析准确，精确度高。可靠性和重现性好而且操作简便，易于推广。
Based on a large number of experiments, a method for quick determination of saccharin sodium salt in foods was established： with glacial acetic acid as solvent, the titration was carried out using standard solution of perchloric acid in glacial acetic acid. Repeated experiments results were 0. 92% --2.93% of RSD and 97.13% -100.3% in revovery rate. It has been found that this method not only has high accuracy, reliability and repetition rate, but also is easy to operate and to be spread in wide range of application.
