镍（Ⅱ）印迹吸附剂去除水中重金属Ni（Ⅱ）的研究

Nickel （Ⅱ） imprinted adsorbent to remove heavy metals in water Ni （Ⅱ） research

近年来重金属的污染已经成为危害最大的水污染之一。镍是一种有毒的重金属元素，镍造成的环境污染受到广泛关注。合成了一种镍（Ⅱ）印迹吸附剂来去除水样中的Ni（Ⅱ），并采用电感耦合等离子体质谱（Inductively Coupled Plasma Mass Spectrometry,ICP-MS）测定水中Ni（Ⅱ）浓度。研究了水体pH值、洗脱条件、吸附时间以及循环使用次数等影响因素。方法的检出限为0．021ug／L。该方法的相对标准偏差为1.13％。地表水样中Ni（Ⅱ）的加标回收率在98％～101％，说明运用Ni（Ⅱ）印迹吸附剂对水中Ni（Ⅱ）的去除效果较好，建立的方法准确可靠。

Pick to： in recent years, heavy metal pollution has become one of the largest water pollution hazards. Nickel is a toxic heavy metal elements, nickel caused by environmental pollution has been widely concerned. Nickel （Ⅱ） was synthesized molecularly imprinted adsorbent to remove Ni （Ⅱ） in water samples, and USES the Inductively Coupled Plasma Mass Spectrometry, Inductively Coupled Plasma Mass Spectrometry, icp-ms）, Ni （Ⅱ） concentration determination in water. Studied the water pH value, elution conditions, influence factors such as adsorption time and cycle times. Method detection limit （including 0.021 μg/L. The method of relative standard deviation is 1.13%. Surface water samples of Ni （Ⅱ） the standard addition recovery rate was 98% - 101%, shows that using the Ni （Ⅱ） imprinted adsorbent for the Ni （Ⅱ） removal effect is better, to establish the method is accurate and reliable.
