本文选用咈咔及其三种9-烃基、六种9-苯基及三种9-苯胺衍生物对七十三种无机离子的分析反应进行研究。在1N 硫酸溶液中咈咔试剂能与 Sb~Ⅲ、Sn~Ⅱ、Sn~Ⅳ、Bi~Ⅲ、Fe~Ⅲ、Ge~Ⅳ、MoO_4~=、WO_4~=等呈橙色至绛红色沉淀,对 Sb~Ⅲ、SnⅡ、Ge~Ⅳ的反应特别灵敏。作者着重研究了试剂对锑(Ⅲ)的比色测定,发现十三种试剂中以9-苯基及9-苯胺-咈咔衍生物的硫酸乙醇溶液可作锑的比色试剂,特别以9-二乙胺基苯及9-间硝基苯-咈咔与三价锑生成之比色液透明清晰,非常稳定,前者测定灵敏度高(可测至0.02γ Sb/ml),后者测定范围大(可测至2γ Sb/ml 以上)。9-间硝基苯试剂测定吐酒石等中锑的含量,与碘量法作比较,误差在百分之一以内。本文还确定试剂与锑的组成此,除试剂Ⅸ、Ⅺ及ⅫⅠ与锑为2:1以外,其余试剂与锑为1:1;试剂Ⅶ、Ⅷ、Ⅺ及ⅫⅠ和锑的络合常数分别为1.92×10~(-7)、5.39×10~(-7)、5.8×10~(-12)及1.8×10~(-12);并初步确定组成1:1络合物的锑是连接于邻二酚基。

The new rapid wet-oxidation method using solution of potassium permanganate in concentrated sulphuric acid (method 1) or concentrated sulphuric acid and aqueous solution of potassium permanganate (method 2) for the destruction of organic matter in Erlenmeyer flask is studied. The samples are dissolved in aqueous solution of sulphuric acid or alkalis which can be heated if necessary, and the solution thus formed is treated rapidly with large excess of oxidant. After the excess oxidant is removed by sodium nitrite and urea, the iodic acid formed is determined in original flask iodometrically. In this method, the new oxidant, a solution of potassium permanganate in concentrated sulphuric acid, is used to complete the destruction of organic matter without heating. The method has been applied to 5 different kinds of samples of various iodine contents, giving satisfactory results in good agreements with those by the Zn reduction method.

A method was described for determining As in organo-arsenic drugs; it was based on iodometric determination of pentavalent arsenic resulting from destruction by the rapid wet-oxidation method. The results obtained by the above method were in good agreement with the standard method described in the literature, but sodium cacodylate could not be decomposed by this method. The characteristics of the solution of potassium permanganate in sulphuric acid in the destruction of organic matter were tested. It was suggested that the content of potassium permanganate in sulphuric acid was not more than 7 per cent.

用快速湿氧化法破坏半微量的样品后,可用碘量法定量地回收五价砷。六种有机砷药物的定量結果与标准方法一致。抗氧化力較强的苯胂酸也能順利地破坏,得到一致的結果,伹不能破坏二甲胂酸。对氧化剂(高錳酸鉀-浓硫酸溶液)破坏有机貭的特性进行了試驗,結果訊为爆鳴系由高錳酸酐(Mn_2O_7)在液面处剧烈分解所致。建議使用浓度为7%以下的氧化剂。先将适量的高錳酸鉀粉末加进样品溶液,再以适量氧化剂溶液处理,可破坏大量有机貭而不引入过多的硫酸。
