摘要
本文研究了磷，砷钼杂多酸－罗丹明６Ｇ荧光猝灭反应，以Ｐ－矩阵计算混合体系中痕量磷和砷。本法灵敏度高，选择性好，简便快速，应用于铜合金中的痕量磷和砷测定，获得满意结果。
The P-Matrix method for simultaneous spectrofluorimetric determination of phosphorus and arsenic was studied. Fluorescence intensity was measured at an excitation wavelength of 350nm and three wavelengths in the range of 550-560nm were selected as emission lines. The calibration was found linear in the range of 0-0.5μg of P (Ⅴ) and 0-2.0μg of As (Ⅴ) in 25ml. The method has been used satisfactorily for the determination of P (Ⅴ) and As (Ⅴ) in copper alloys.
