摘要
研究了原子荧光光谱法测定铅锌精矿中汞的分析方法。考察了原子化温度、灯电流、负高压、载气流量、延迟时间等仪器条件,也进行了测定介质与酸度、硼氢化钾与氢氧化钾浓度、工作曲线线性、共存元素干扰等条件试验。该方法操作简单、准确、灵敏度高。应用于铅锌精矿中汞的分析,线性范围为0 05～1μg/100mL,回收率为95%～106%,RSD≤5%。
In this article the analytical method of mercury in LeadZinc concentrate ore in atomic fluorescent spectrometry was studied,The instrument conditions like atomiclize temperature?lamp current?nagative high voltage?carrier gas flow rate and delay time were checked,The medium,acidity?density of postassium borohydride and sodium hydroxide?linearity of the work curve and coexistence interference elements were tested.It is easy operation?precise and high delicacy.the linear rang is 005～1?μg/100?mL,the recovery rate is 95%≤5% in application.
