摘要
本文利用流动注射荧光法研究砷、硅钼杂多酸与罗开明6G的荧光猝灭反应，利用此反应测定了痕量砷、硅，该方法灵敏度高，选择性好，分析速度可达120样／小时，本法应用子铜合金中痕量砷、硅的测定，取得满意结果。
A fhw injetion analysis method for trace amount of As and Si determination is established ,basing on Rhodamine 6G formation of an uvfluorometric ion－association complex． Fluorescence is measuerd at 555um（excitation 350um）The calibration graph is rectilinear for 0－100μg／ml of arsenli and 0-80μg／ml of silicon．The method is used for determination of As（V）and Si（IV） in copper alloy with satisfying result．
