Abstract: II) ion imprinted magnetic composite adsorbent (Cu(II)-IMB) was synthesized by ion imprinting technique in order to improve the selective adsorption for certain heavy ions. SEM,EDX,XRD,FTIR and VSM were used to study the structure identification of Cu(II)-IMB and its components. The selective adsorption and other physical characters of the composite adsorbent were stdudied. Results show that Cu(II)-IMB has high selective adsorption for Cu(II) in water,and its adsorption capacity can be improved by 24%,33% and 54% in contrast to NIMB,CMB and MB,respectively. The adsorption capacity is decreased by 14% after reuse for five times. This new adsorbent has a good mechanical intensity and reuse,it has magnetism and can be separated from solution quickly after adsorption. It is concluded that Cu(II)-IMB is low and mass-produced.
