已有报道用极谱法直接测定汽水中的糖精钠〔１〕，而对固体样品和部分成分复杂的液体或半固体样品，仍需先透析后沉淀，再用乙醚提取法作样品前处理，最后用极谱法测定〔２〕。本文尝试简化样品处理过程，在Ｃｕ２＋大量存在下测定样品中的糖精钠，结果满意。现报告如下。... It has been reported using polarography to directly measure sodium saccharin in soft drinks [1]. However, for solid samples and some liquid or semi-solid samples with complicated components, dialysis and precipitation are still required before the samples are extracted by ether extraction. Finally, polarographic determination 〔2〕. This paper attempts to simplify the sample processing, determination of sodium saccharin in the presence of Cu2 +, with satisfactory results. The report is as follows. ...
