Abstract
Interactions of Cd (II) ion in solution with the adsorbent of amino-silica hybrid or non-imprinted polymer (NIP) and Cd (II) ionic imprinting (Cd (II)-IIP) have been studied through a sequential desorption process. The adsorbent of NIP and Cd (II)-IIP were synthesized from 3-aminopropyltrimethoxysilane (3-APTMS) and tetraethylortosilicate (TEOS). The value of the Specific surface area, total porous volume, and Cd (II)-IIP porous diameter is each 29.010 m2 g-1, 0.100 mL g-1, and 30.452 Å. The interaction contribution of Cd (II) ion was determined by the sequential desorption with water eluent, KNO3 1 M, HONH2HCl 0.3 M in 25 % (v/v) CH3COOH, and Na2EDTA 0.1 M. The sequential desorption result showed that a tendency of Cd (II) ion interaction contribution on NIP and Cd (II)-IIP increased with order of ion exchange interaction < entrapment < complex formation < hydrogen bond.
