摘　　要：在4mol/L的硫酸介质中,丁基罗丹明B与InBr4-形成的三元缔合物在550nm处发射出强烈的荧光,由此而进行荧光光度法测定铟。此方法系统地研究了丁基罗丹明B与InBr4-形成的三元缔合物的测定条件及干扰元素的影响,测定下限为0.01μg/mL,结果满意。Ternary associated compound which is formed by butyl rhodamine B and InBr-4 emits strong fluorescent light at 550nm in 4mol/L sulphuric acid medium,thereby determining indium through fluorophotometry,the method systematically studies the determining conditions of the ternary associated compound which is formed by butyl rhodamine B and InBr-4 and the influence of interference elements,the detection limit is 0.01μg/mL,and the result is satisfied.
