Nghiên cứu sự tạo phức đơn và đa dạng đa ligan của Sm (III) với metyl thymol xanh (MTB) và axit tricloaxetic (CCl3COOH), axit sunfosalixilic

SUMMARY A study on the complexation of the mono- and multiligand complexes of Sm(III) with methyl thymol blue (MTB) and HnX(HnX : CCl3COOH, sulphosalycilic acid) TRAN THI HONG VAN, NGO HUONG LY The mono- and multiligand complexation in the system Sm(III)-MTB and Sm(III)- MTB-HnX has been studied by the spectrophotometric method. The optimal conditons, the compotion and quantitative parameters of both complexes have been determined. The multiligand complexes may be used to increase the sensibility of the spectrophotometric determination of samarium micro quantity.
