Complexation Of The Fe(iii) And Fe(ii) Sulphates With Diphenyl-4-amine Barium Sulphonate (das) Synthesis, Thermogravimetric And Spectroscopic Studies

Reactions in aqueous-alcoholic solution between diphenyl-4-amine barium sulphonate (Ba-DAS-anionic surfactant) and the hydrated sulphates of Fe(III) and Fe(II) ions and their use to ovtain iron oxides are described here. The formation of Fe(II) complexes was reached by using an excess of Ba-DAS, in absence of light under inert atmosphere. The complexes achieved Fe 2[(C12H10NO3S)4] •9H2O and Fe3[(C12H10NO 3S)6]•12H2O were characterized by TG/DTG and IR, UV-VIS and 57Fe-Mössbauer analyses.971289296Zhonghua, W., Lin, G., Qianshu, L.,
