摘要: Abstract Benzil derivative of polyacrylohydrazide was used as a new sorbent for preconcentration silver ion from aqueous sample solutions. The results confirmed the strong affinity and selectivity well fast equilibration interaction processes toward Ag + . All experimental parameters such amount solid sorbent, pH solution, solution flow rate eluent were optimized. Thiourea has been in order to selectively desorb adsorbed surface sorbent. Flame atomic absorption spectrometry determination other metal ions. EDTA, masking agent, prevented interferences Fe 3+ , Ni 2+ or Zn while allowing quantitative extraction enrichment factor about 100 R.S.D. found be 5.3%. method successfully applied separation some silver-spiked water samples.
