A New Method for Spectrophotometric Determination of Trace Mercury Ⅱ.On the Complex Formation Reaction of Manganese (Ⅱ) with Tetra-(P-trimethylammoniumphenyl porphine lodide

Xie Nengyong Xu Mianyi Pan Zuting Miao Jianwei (Chemistry Department of Wuhan University)  
The complex formation of manganese(Ⅱ)with tetra-(p-trimethylammo-niumphenyl)porphine iodide〔TAPP〕is accelerated by mercuric ion. As low as 10~(-8)mol. dm~(-3) of mercury(Ⅱ)can be determined from the decrease in absorbance at 411 nm(λ_(max) of TAPP)at a fix time after the initiation of the reaction of manganese(Ⅱ)with TAPP at 60℃ in a weak acidic medium. Sandell′s sensitivity is calculated to be 1.6×10~(-2) ng cm~(-2). with the separation of mercury(Ⅱ)by sulfhydryl-cotton fiber at room temperature, the method is highly selective and free from interference of most substances.
