【摘要】 对测定水和废水中铅含量的氢化物发生-原子荧光光度法进行了实验研究,该方法具有灵敏度高、干扰少、操作简便等优点,优化了测定水和废水中铅的条件,对Fe3+、Mn2+、Ni2+、Hg2+、Zn2+、Cr6+、Cu2+、Cd2+等金属离子的干扰情况进行了实验,并对高、中、低浓度的标准物质和废污水进行了一系列测定,实验结果令人满意。更多还原

【Abstract】 A method is reported for determination of lead in water and wasted water by hydride generation-atomic fluorescence method. The best condition for the determination and the interference from coexistent elements such as Fe3+, Mn2+, Ni2+, Hg2+, Zn2+, Cr6+, Cu2+ and Cd2+ in water are studied. In the given conditions, the detecting limit is 0.76μg/L, the recovery rate of the known sample is 95.1%～108% and the relative standard deviation is less than 5%. The result is satisfying.更多还原
