中文摘要：

制备了一种新型吸附材料一离子印迹聚合物，优化了对痕量Ni2＋的吸附与解吸条件．在pH一7．0、流速为4．0mL／min的条件下，离子印迹聚合物能定量吸附试液中的痕量Ni2＋，其动态饱和吸附容量为7．38mg／g．吸附在离子印迹聚合物上的Ni2＋可用5mL1．0mol／LHCl完全洗脱．该方法的检出限为0．26μg／L，线性范围为0．1～5．0,ug／mL，相对标准偏差为1．91％（1．0,ug／mLNi2＋），方法用于环境水样中痕量镍的测定，结果满意．

英文摘要：

In this paper, ion-imprinted polymer as a new sorbent was synthesized. The conditions of ad- sorption and desorption for trace nickel were optimized. At pH 7.0 and flow rate 4.0 mL/min, nickel could be quantitatively adsorbed by ion-imprinted polymer, and the dynamic adsorption capacity was 7.38 mg/g. The adsorbed nickel could be eluted from the absorbent with 5 mL 1.0 mol/L HC1. The linear range was 0.15.0 /Lg/mL with a detection limit {3a, n =11） of 0.26/g/L. The RSD {n =7} for determination of 1.0 btg/mL Niz＋ was 1.91%. The method was applied in the determination of trace nickel in environment water with satisfactory results.
