The influence of sorption characteristics on the removal of silver(I) has been examined. The sorption capacity of chelating polymeric sorbent, based on maleic anhydride styrene copolymer modified with m-aminophenol, towards Ag(I) ions was studied. The pH of sorption was maximum at the value 6. With the increasing of initial metal concentration, sorption of silver(I) increases and reached maxima at val-ue 80∙10-3 M. At the final stage, the elution process of Ag(I) was established and find that HNO3 1 M is the best elution agent. Multiple use of the regenerated sorbent for sorption process is possible. This study shows that using of mentioned sorbent modified with m-aminophenol is effective for removal of silver(I) ions from aqueous solutions

Co-sorption characteristics of Zn(II) and As(V) on the mixed Fe/Al-PILCs was investigated in a batch system at room temperature. The effects of relevant parameters, such as pH value of solution, adsorbent dosage, initial Zn(II) and As(V) concentrations and contact time were examined, respectively. The results show that co-sorption capacities and co-sorption rates of Zn(II) and As(V) by Fe/Al-PILC are higher and faster than those of single Zn(II) or single As(V) by Fe/Al-PILC. Co-sorption isotherm data of Zn(II) and As(V) by Fe-Al-PILC were fitted well to Langmuir isotherm and the maximum sorption capacities of Zn(II) and As(V) on mixed Fe-Al-PILCs (Q0) are 16.98 mg/g and 16.29 mg/g, respectively, which are higher than those in single system. n>1 from Freundlich isotherm indicate that the sorption of Zn(II) and As(V) by Fe-Al-PILC is favorable. E values from D-R model indicate that the type of sorption of Zn(II) and As(V) by Fe-Al-PILC is physical. The results indicate that there is significant potential for Fe/Al-PILCs as an adsorbent material for Zn(II) and As(V) removal from aqueous solutions.
