摘要
本文将流动注射分析(FIA)引入Mo-SCN^--RhB三元缔合体系测定痕量Mo。不需萃取,反应迅速,重现性好。0～1.6μg/ml Mo符合比耳定律,检测限0.02μg/ml。用预混线圈R_1可克服Fe^(3+)等元素与SCN^-络合的干扰。测定了植物中Mo,结果满意。
A method of flow injection analysis (FIA) was introduced into the spectrophotometric system of Mo-SCN^--RhB ternary complex for the determination of trace Mo. This method does not need preliminary extraction, and was a rapid, reproducible one, Beer's law was obeyed within the range from 0.00 to 1.60 μg/ml for Mo, and the detection Iimit was 0.02 μg/ml. The loop R_1 was used so that the interference of iron complex could be eliminated. The determination of Mo in plants was carried out with satisfactory results.
