桑色素(Morin)荧光光度法测定铝早就被研究,但采用固体表面荧光法的测定研究却未曾见报导.我们使用YF-1型荧光计,找出铝—桑色素配合物在滤纸基质上的最佳生成条件及测试条件,并用于铜合金中铝的测定,获得了满意的结果.一、主要试剂及仪器铝标准溶液(1.0mg/ml):称取0.5000g金属铝(AR),用少量浓HCl加热溶解,以1mol/L NaOH中和至弱酸性,加水定容500ml.使用时稀释至所需浓度并调节至适当的pH值; Morin fluorimetry has long been studied for aluminum, but studies using solid surface fluorometry have not been reported. We used the YF-1 fluorometer to find out that aluminum-morin complex on the filter paper substrate The best conditions and test conditions, and for the determination of aluminum in copper alloy, and obtained satisfactory results.And the main reagents and equipment aluminum standard solution (1.0mg / ml): Weigh 0.5000g aluminum (AR) With a small amount of concentrated HCl heating to dissolve, neutralized with 1mol / L NaOH to weak acid, add water constant volume 500ml.Use diluted to the desired concentration and adjusted to the appropriate pH value;
