Synthesis a new adsorbent of molecularly imprinted polymer for absorb the silver ions from biological sample

Abstract

This work reports the preparation of molecularly imprinted polymer (MIP) particles for selective extraction and determination of silver ions from aqueous media. Various parameters were optimized, such as pH, time, concentration of sample and type of eluent for elution of silver from polymer. Also Interfering effect was investigated on the absorption of silver by molecularly imprinted polymer. At the end, MIP verified specific selectivity of template molecule with the high detection limit. Finally, silver was preconcentrated by the synthesized molecularly imprinted in the saliva after applying of antiseptic solution. Results were compared with the obtained results by ICP method. The results showed high performance of this method in pre-concentration of silver.
