3급 아민염 및 4급 암모늄염의 Tetrathiocyanatocobaltate[II]에 의한 분석화학적 연구

Studies on the Chemical Analysis of the Tertiary Amine Salt and Quaternary Ammonium Salt by Tetrathiocyanatocobaltate[II]

Tetrathiocyanatocobaltate[II] forms complexes with tertiary amine salts or quaternary ammonium salts which were extractable from aqueous solution by organic solvent. In order to study composition of the conplex, the colored crystalline complexes produced were evaluated with elemental analysis, infrared and mass spectra. And also a novel spectrophotometric method for the determination of tertiary amine salt or quaternary ammonium salt with tetrathiocyanatocobaltate[II] was established by organic solvent extraction within coefficient of variation of 1.06~1.35%.
