摘要
研究用对马尿酸偶氮氯膦试剂光度法测定铝合金铈组稀土总重。络合物最大吸收峰为680nm,有很高的灵敏度和稳定性。该方法已应用于2024铝合金材料的分析。
P-Aminohippuric Acid chlorophosphonazo red in acidic medium and reacts with RE to form blue-vi-olet complexs,which gives a high absorption at 680nm.This proposed method has high selectivity,stabili-ty and sensitiveness and has been successfully applied to determine the Total RE in 2024 Aluminium alloyswith satisfactory results.
