摘要
采用活性炭吸附原子吸收法测金含量时,铅对检测结果有极大干扰,针对铅对活性炭吸附原子吸收法测金的影响,通过实验探讨温度、酸度、Na2SO4加入量对检测结果影响,并提出改进方法,有效消除了铅的干扰,提高了检测结果的准确性及精密度.
Abstract
When using activated carbon adsorption atomic absorption method to measure gold content,lead has a great interference on the detection results.In order to address the influence of lead on the detection of gold using activated carbon adsorption atomic absorption method,the influence of temperature,acidity,and Na2SO4 addition on the detection results is explored through experiments,and improvement methods are proposed to effectively eliminate the interference of lead and improve the accuracy and precision of the detection results.
