Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - From hydrochloric acid solutions extracted metal cations Cd(II) and Hg(II) after change into chloroanion complexes as ion pair association complexes by using many organic reagents as complexing agent according to liquid ion exchange method it was -Naphthyl amine ( -NA), 4-Amino benzoic acid (4-ABA), 2-[(4-Carboxy methyl phenyl)azo]-4,5-diphenyl imidazole (4-CMePADPI) and Cryptand C222, among the optimum conditions definition the laboratory experimental studies shows there was different optimum concentrations of hydrochloric acid HCl in the aqueous solutions according to the kind of organic reagent used,shaking times for the two phases, so that the research involved many other studies for instances electrolyte, interferences and organic solvent effect, in the side of thermodynamic study appear liquid ion exchange for extraction Cd(II) was exothermic by using -NA and C222 but endothermic with 4-ABA and 4-CMePADPI, whereas extraction Hg(II) demonstrate the method was exothermic by using 4-ABA, 4-CMePADPI and C222 but endothermic with -NA. Stoichiometry showed the complexes extracted was 1:1:1 Cation:Organic reagent:Anion.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Separation and preconcentration via of liquid ion exchange which is one of solvent extraction application was very important as separation method. This book involves the applicability of liquid ion exchange by using of super molecules such as crown ethers such as 12C4, 15C5,18C6, DB18C6, DCH18C6, DB24C8 and cryptands C221, C222 in presence of alkali and alkaline earth metal cation to form liquid ion exchanger used to extract chloroanion complexes of Pb (II) and Al (III). Chloroform used as an organic solvent to dissolve crown ethers and cryptands. Pb (II) extracted from HCl media, whereas Al (III) from neutral media. As well prepared calibration curves for spectrophotometric determination of metal ions under study in environmental and vital samples, the different samples were prepared according to wet digestion method. 232 pp. Englisch.
