摘要
在pH 10.6的乙二胺底液中,可获得稀土-茜素络合剂的络合吸附波。可用于测定发光材料BaCl F:Gd中的钆含量。测得电活性络合物为RE(Ⅲ):ALC=1:2的单核络合物。
In a supporting electrolyte containing alizarin complexon 1.6×10-4mol/L, KGl 0.02 mol/L, ethylene diamime 2%, at pH 10.6, excepting Er(Ⅲ), Tm(Ⅲ), Yb(Ⅲ), Lu(Ⅲ), the adsorptive complex wave of the rare earth ion-ALC has been ohtai- ned. The CLa from 6.0×10-7 to 4.0×10-5 mol/L and the CRE of the other rare earth ions from 6.0×10-5 to 7.0×10-5 mol/L are directly proportional to the peak height of adsorptive complex wave. The gadolinium content in luminesent material (BaCIF:Gd) has been determined. The electroactive complex has been detected as RE(ALC)23-·
