Carrier element-free coprecipitation (CEFC) method for the separation, preconcentration and speciation of chromium using an isatin derivative
(Analytica Chimica Acta, 2009)
A new, simple, rapid and sensitive separation, preconcentration and speciation procedure for chromium in environmental liquid and solid samples has been established. The present speciation procedure for Cr(III) and Cr(VI) ...
Evaluation of Adsorption Characteristics of Malachite Green onto Almond Shell (Prunus dulcis)
(Separation Science and Technology, 2010)
The potential usage of almond shell (P. dulcis), which is an agricultural waste product, in the removal of malachite green from aqueous solutions was evaluated with respect to various experimental parameters including ...
Carrier element-free coprecipitation with 3-phenly-4-o-hydroxybenzylidenamino-4,5-dihydro-1,2,4-triazole-5-one for separation/preconcentration of Cr(III), Fe(III), Pb(II) and Zn(II) from aqueous solutions
(Journal of Hazardous Materials, 2009)
A separation/preconcentration procedure, based on the coprecipitation of Cr3+, Fe3+, Pb2+ and Zn2+ ions using a new organic coprecipitant, 3-phenly-4-o-hydroxybenzylidenamino-4,5-dihydro-1,2,4-triazole-5-one (POHBAT) without ...
Selective Separation, Preconcentration and Determination of Au(III) ions in Environmental Samples by Coprecipitation with a 1,2,4- Triazole Derivative
(Atomic Spectroscopy, 2013)
An effective, simple, lowcost, and accurate separation and preconcentration procedure which has minimal impact on the environment has been developed. It is based on the carrier element-free coprecipitation (CEFC) of ...
Tea-industry waste activated carbon, as a novel adsorbent, for separation, preconcentration and speciation of chromium
(Analytica Chimica Acta, 2011)
Activated carbon was produced from tea-industry wastes (TIWAC) and employed as a low cost and effective solid phase material for the separation, preconcentration and speciation of chromium species without using a complexing ...
Removal of phenol from aqueous solution by adsorption onto organomodified Tirebolu Bentonite: Equilibrium, kinetic and thermodynamic study
(Journal of Hazardous Materials, 2009)
A natural bentonite modified with a cationic surfactant, cetyl trimethylammonium bromide (CTAB), was used as an adsorbent for removal of phenol from aqueous solutions. The natural and modified bentonites (organobentonite) ...
Kinetics, Thermodynamics and Equilibrium Evaluation of Adsorptive Removal of Methylene Blue onto Natural Illitic Clay Mineral
(Desalination and Water Treatment, 2014)
The natural illitic clay mineral (NICM) has been used as a low cost and highly effective adsorbent in the removal of a toxic cationic dye, methylene blue (MB), from aqueous solution by a batch adsorption technique. The ...
Biosorption of Rhodamine 6G from aqueous solutions onto almond shell (Prunus dulcis) as a low cost biosorbent
(Desalination, 2010)
This work presents an alternative methodology for removal of a dyestuff, Rhodamine 6G (R6G), from aqueous solutions by using a new biosorbent, almond shell (Prunus dulcis), in a batch biosorption technique. The characterization ...
