Preconcentration of Palladium (II) by Chelateforming Sorbent and Its Photometric Determination With 2,2',3,4-Tetrahydro-3 -Sulpho-5 -Chlorazobenzol
Öz
The complex formation of palladium(II) with 2,2',3,4-tetraxydroxy-3 -sulpho-5 - chlorazobenzol was studied. Homogenous complex with 1 2 molar ratio of components there was formed, maximum light absorption of complex was observed at 474 nm, molar coefficient of absorption is (2.00±0.02)·104 . It was produced a new sorbent containing carboxyl group. A static sorption capacity on K+ ions was studied and the constants of ionization of ionogenic groups were determined by potentiometric titration. It was made an izoterm of sorption of palladium with that
sorbent and there were investigated a condition of concentration. The degree of extraction of Pd (II) ions at optimal conditions is more than 96%. Limits of detection (3 , n=20) are 14.2 ng/ml. The technique is used to determine palladium in standard bismuth-polymetallic sample.
