Studies on the Extraction of Mn (II) by Tri-capryl Amine Oxide

Tri- Capryl amine Oxide (TCAO) in benzene has been used as extractant for the extraction of Mn (II) from aqueous acid solutions. The extractions are found quantitative from hydrochloric and sulphuric acid solutions and partial from nitric acid solutions. Various factors - acidity, metal ion, extractant concentration and influence of other ions etc. on the extraction process has been studied. Solvated extracted species is also suggested. Estimation of manganese in food and pharmaceutical samples has been achieved successfully.
