合成了一个新的二安替比林试剂，二安替比林对溴苯基甲烷（ＤＡｐＢＭ），并研究了它和Ｍｎ（Ⅶ）的显色条件．在磷酸介质中，Ｍｎ（Ⅱ）存在下，ＤＡｐＢＭ和Ｍｎ（Ⅶ）生成橙色产物，λｍａｘ＝４８０ｎｍ，ε＝１．２８×１０６Ｌ（ｍｏｌｃｍ）－１，锰的含量在０．１－０．９μｇ／２５ｍｌ内符合比尔定律．用于食品和水样中锰的测定，结果满意
A new diantipyryl reagent, diantipyryl p-bromophenylmethane (DApBM) was synthesized and its color development conditions were studied. In the presence of Mn (Ⅱ), DApBM and Mn (Ⅶ) produce orange product in phosphate medium with λmax = 480nm and ε = 1.28 × 106L (molcm) -1. The content of manganese is 0.1-0.9μg / 25ml within the Bill’s law. For food and water samples of manganese determination, the results are satisfactory
