STUDY ON SORPTION OF SOME TOXIC AND HEAVY IONS IN DILUTE SOLUTIONS BY CLINOPTILOLITE
The deposits of clinoptilolite (CLI) in Iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. The results showed that the absorption for Ca2+ (7.5 ppm), Cu2+ (50 ppm), Zn2+ (40 ppm), Cd2+ (40 ppm), Pb2+ (500 ppm) and Al3+ (5 ppm) were 95.2, 96.70, 93.30,99.12, 99.2 and 90.0 percents, respectively. The noteworth...
متن کاملSeparation of Metal Bis(2-hydroxyethyl)dithiocarbamate Complexes by Micellar Electrokinetic Capillary Chromatography
A method was developed for the separation of CdII, PbII, PtII, CoII, NiII, BiIII, CrII, CuII and HgII bis(2-hydroxyethyl)dithiocarbamate (HEDTC) complexes by micellar electrokinetic capillary chromatography. The complexes were formed by pre-capillary reaction of the metal ions with an excess of the ligand and then separated using a 100 mm borate buffer (pH 9.2) containing 4% methanol (v/v), 10 ...
متن کاملSynthesis of a dehydroabietyl derivative bearing a 2-(2'-hydroxyphenyl)benzimidazole unit and its selective Cu²+ chemosensing.
A dehydroabietyl derivative 2 bearing a 2-(2'-hydroxyphenyl)benzimidazole unit was synthesized and its sensing behaviors toward metal ions were investigated by UV-Vis and fluorescence spectroscopy methods. In THF solution, compound 2 exhibited excellent selectivity for CuII over miscellaneous other metal ions including CrII, MnII, CoII, NiII, ZnII, CdII, AlIII, MgII, PbII, HgII, NaI, LiI and KI...

متن کاملAdsorption Mechanism of Toxic Metal Ions by Clay (attapulgite)
A series of adsorption tests were conducted to analyze the sorption capacity of attapulgite. Ions such as cobalt, nickel, lead and cadmium were adsorbed from waste solutions onto attapulgite surface. Adsorption depletion tests were performed as a function of solid to liquid ratio, conditioning time, heavy metal ion concentration, and pH to identify the mode and extent of interactions in the sys...
