Özet

N,N-dibutyl-N (1)-benzoylthiourea (DBBT) impregnated onto a polymeric matrix, Amberlite XAD-16 was prepared. The separation and enrichment of Ag(I) from solution was investigated. Effective extraction conditions were optimized in column methods prior to determination by atomic absorption spectrometry. The optimum pH range for quantitative adsorption is 2-5. Quantitative recovery of Ag was achieved by stripping with 1mol L-1 thiourea in 1mol L-1 HCl. The sorption capacity of resin is 0.115mmol Ag+ g(-1) resin. The relative standard deviation and detection limit was 3.1% for 1A mu g Ag+ mL(-1) solution and 0.11A mu g L-1, respectively. The method was used for the determination of silver in geological water samples.
