Interactions of Cd (II) ion in solution with the adsorbent amino-silica hybrid or non-imprinted polymer (NIP) and ionic imprinting (Cd (II)-IIP) have been studied through a sequential desorption process.The NIP (II)-IIP were synthesized from 3-aminopropyltrimethoxysilane (3-APTMS) tetraethylortosilicate (TEOS).The value Specific surface area, total porous volume, diameter is each 29.010 m 2 g -1 , 0.100 mL 30.452Å.The interaction contribution was determined by water eluent, KNO3 1 M, HONH2HCl 0.3 M 25 % (v/v) CH3COOH, Na2EDTA 0.1 M. The result showed that tendency on increased order exchange < entrapment complex formation hydrogen bond.
