二安替比林邻乙氧基苯基甲烷光度法测定锰尹家元杨光宇王亮徐其亨目前锰的测定常用高锰酸盐光度法［１］，该方法灵敏度低。二安替比林甲烷芳香族衍生物能被高价金属离子氧化显深色［２，３］，并用作这类金属离子的显色剂。在研究二安替比林３，４，二甲氧基苯基甲烷（Ｄ... Determination of Manganese Yin Jiayuan Yang Guangyu Wang Liang Xu Qiheng Manganese commonly used in the determination of permanganate spectrophotometry [1], the sensitivity of the method is low. Diantipyryl Methamitha aromatic derivatives can be oxidized by expensive metal ions to give a dark color [2,3] and are used as color-developing agents for such metal ions. In the study of two antipyrine 3,4, dimethoxy phenyl methane (D ...
