| Abstract: | ABSTRACT In this study, Zn(II) ion-imprinted polymer was prepared on the surface of vinyl silica particles and applied for detection of Zn(II) ions using differential pulse voltametry. The ion- imprinted polymer particles were prepared by free radical polymerization. The prepared particles were characterized by different morphological and elemental techniques. The ion-imprinted particles were used to fabricate the carbon paste electrode as a zinc ions sensor. The modified zinc sensor showed linear response in the concentration range 6.12 × 10?9 to 4.59 × 10?8 mol L?1. The limit of detection and limit of quantification of the electrode were 1.351 × 10?8 and 4.094 × 10?8 mol L?1, respectively. |
