Spectrophotometric Determination of Silver by New Azodyes Deriven From 2-Thiobarbituric Acid Partll: Silver Complexes


This study describe the use of new azodyes reagents 5-( 2,3dihydro-1,4-phathalezindionazo) -2thiobarbituric acid ( L1 ) and 5-(2-thiobarbituric acid azo )-phenyl-4-acetic acid (L2) as sensitive and selective analytical reagents for the determination of Ag(I) spectrophotometrically. L1 and L2 react with Ag at pH ( 9 and 10 ) respectively to form colored… (More)
