Spectrophotometric Determination of Nickel(II) and Palladium(II) by Preliminary Adsorption of their 1-Phenyl-3-(2-thiazolyl)thiourea Complex on Polyurethane Foam

Department of Applied Chemistry & Chemical Technology, Maharshi Dayanand Saraswati University, Ajrner-305 001 Manuscript received 21 June 1996, revised 6 August /996, accepted 19 August 1996 A new spectrophotometric method for the determination of nickel(II) and palladium(II) after adsorption of their 1-phenyl-3-(2-thiazolyl)thiourea complex on polyurethane foam is discussed. The method has been applied to the determination of nickel(II) in hydrogenated oil and palladium(II) in synthetic samples
