用萃取光度或萃取荧光法研究稀土-桑色素(Mor)络合物已有一些报道,认为只能在弱酸性条件下形成不太稳定的络合物。用电分析化学方法研究稀土-桑色素络合物尚未见报道。我们在乙二胺(en)-KCl底液中得到了该体系的络合吸附波,研究了过程的机理并用于测定发光材料中的钆。
Studies on extraction of rare earth-morin (Mor) complexes by extraction spectrophotometry or extraction fluorescence have been reported, and it is believed that they can form less stable complexes under weakly acidic conditions. Electroanalytical chemistry has not been reported for the rare earth-morin complex. We obtained the complex adsorption wave of this system in ethylenediamine (en) -KCl bottom solution. The mechanism of the process was studied and used to determine gadolinium in luminescent materials.
