| 摘 要： | 研究了用氢化物发生-原子荧光法测定生活废水中微量汞的最佳实验条件及其测定微量汞的方法.此法是在硝酸介质中,以硼氢化钾作还原剂,将被测元素转化为挥发性氢化物,以高纯氩气作为载气将挥发性气氢化物从母液分离,并导入石英炉原子化器中原子化.以空心阴极灯作激发光源,激发被测元素原子发出荧光,其荧光强度在一定范围内与被测元素的浓度成正比.该方法简便、快速、准确.

| Abstract: | The best experimental condition and method for testing trace mercury in domestic wastewater were studied through hydride generation atomic fluorescence spectrometry(HG-AFS)in this paper.In the nitric acid medium,being the potassium borohydride as reductant,the testing elements were thransformed with volatile hydride,and the volatile hydride was extracted from the mother liquor,with using high purity argon as carrier gas,then injected in the quartz tube furnace atomizer.The hollow cathode lamp was exploited to excitated testing elements as to emit fluorescence,its fluorescence intensity was directly proportional with the concentration of the elements.This method is simple,quick and accurate. |
