摘　　要：　Al3+能同许多有机试剂形成会发出荧光的荧光络合物。8—羟基喹啉与Al3+所形成的络合物被氯仿萃取,萃取液在365nm激发光的照射下产生荧光,其发射光峰值波长在507nm处,以此建立海水中铝的荧光测定方法。Ion Al^(3+) can react with many organic reagents to produce fluorescence complex compounds which can emit fluorescence.If the complex compound produced in the reaction between 8-hydroxyquinoline and ion Al^(3+) is extracted by chloroform,the obtained liquid will emit fluorescence while it is excitated by ray at 365nm.The emission ray peak is at wavelength 507nm.The method of determination of aluminum in the seawater is established on the basis of this fact.
