MICELLAR EFFECT ON METAL-LIGAND COMPLEXES OF Co(II), Ni(II), Cu(II) AND Zn(II) WITH CITRIC ACID

来源出版物: BULLETIN OF THE CHEMICAL SOCIETY OF ETHIOPIA    卷: 23    期: 3    页: 347-358    出版年: DEC 2009   
摘要: Chemical speciation of citric acid complexes of Co(II), Ni(II), Cu(II) and Zn(II) was investigated pH-metrically in 0.0-2.5% anionic, cationic and neutral micellar media. The primary alkalimetric data were pruned with SCPHD program. The existence of different binary species was established from modeling studies using the computer program MINIQUAD75. Alkalimetric titrations were carried out in different relative concentrations (M:L:X = 1:2:5, 1:3:5, 1:5:3) of metal (M) to citric acid. The selection of best chemical models was based on statistical parameters and residual analysis. The species detected were MLH, ML2, ML2H and ML2H2. The trend in variation of stability constants with change in mole fraction of the medium is explained on the basis of electrostatic and non-electrostatic forces. Distributions of the species with pH at different compositions of micellar media are also presented

能不能吧文献都下下来  放到纳米盘上
