説明

Di- (p-bromophenyl) thiocarbazone and di- (o-bromophenyl) thiocarbazone are synthesized and their fundamental properties have been investigated. The maximum absorption wave length of p-bromo derivative and its metal complex solution shifted to a longer wave length side than in the case of dithizone, while o-bromo derivative and its metal complex solution shifted to a shorter side. The reactivity of o-bromo derivative to metal ions is lower than that of dithizone. The molecular extinction coefficients of both derivatives and their metal complex solution at their maximum absorption wave length have been estimated. The molecular extinction coefficient of the solution of p-bromo derivative is larger than that of dithizone, while that of o-bromo derivative is smaller. The change of the molecular extinction coefficient of each metal complex solution did not show a uniform tendency. Also, the extraction coefficients of Hg2+ and Cu2+complexes have been estimated and the discussions were made on their changes.
