摘要
研究了在碱性介质中，Ｍｎ（Ⅱ）被空气氧化为Ｍｎ（Ⅳ）．然后在磷酸介质中，Ｎｉ（Ⅱ）和阳离子型Ｏ／Ｗ（ＣＴＭＡＢ／ｎ－Ｃ５Ｈ１１ＯＨ／ｎ－Ｃ７Ｈ１６／Ｈ２Ｏ）表面活性剂存在下，Ｍｎ（Ⅳ）氧化二安替比林对氧苯基甲烷（ＤＡｐＣＭ）生成橙色产物，４８０ｎｍ，ε＝１．３８ｘ１０５．锰的含量在０－４００ｕｇ／Ｌ内符合比尔定律。用于合金和矿石中锰的测定，结果满意。
In the alkaline medium Mn(Ⅱ) was oxidized to Mn(Ⅳ)by air. Diantipyryl-(p-chloro)phenylmethane* (DApCM)can reacts with Mn(Ⅳ) to form a orange product in the presence of Ni(Ⅱ),(CTMAB/n-C5H11OH/n-C7H16H2O)* and phosphoric acid medium.The molar absorptivity is 1.38x105L·mol-1·cm-1 at 480nm. Beer',s law is obeyed in the* range of 0-400ug/L. method can be applied to the determination of manganese in ore and alloy with satisfactory results.*
