6-phenyl-2,3-dihydro-assym-triazine-3-thione and 5,6-diphenyl-2,3- dihydro-asym-triazine-3-thione as gravimetric reagents for the determination of thallium and palladium.

Abstract

The analytical use of 6-phenyl-2,3-dihydro-asym-triazine-3-thione (PDTT) and 5,6-diphenyl-2,3-dihydro-asym-triazine-3-thione (DDTT) has been investigated. PDTT proved to be suitable for the determination of thallium(I) in the presence of cyanide whereas DDTT is more selective than PDTT in alkaline tartrate solution and is applied for the selective gravimetric determination of palladium. The method is more sensitive than the dimethylglyoxime method. The only metal ions interfering are Hg(II), Ag and Tl(I).
