Adsorption of Cu(II) onto silica gel-immobilized Schiff base derivative
(Elsevier, 2009)
4-chloroisonitroacetophenone 4-aminobenzylhydrazone (CAAH) chemically anchored on a silica gel surface, has been used for Cu(II) sorption from aqueous solution. The surface modification processes was performed after ...
Plasma treatment of polypropylene fabric for improved dyeability with soluble textile dyestuff
(Elsevier, 2009)
The impact of plasma treatment parameters on the surface morphology, physical-chemical, and dyeing properties of polypropylene (PP) using anionic and cationic dyestuffs were investigated in this study. Argon plasma treatment ...
Metal complexes and solvent extraction properties of isonitrosoacetophenone 2-aminobenzoylhydrazone
(Pergamon-Elsevier Science Ltd, 2006)
Three types of copper complexes as well as an oximate-bridged nickel complex with isonitrosoacetophenone 2-aminobenzoylhydrazone (H2L) have been prepared in ethanolic solution and characterized by elemental analyses, IR, ...
Antioxidant and Anticholinesterase Activity Evaluation of ent-Kaurane Diterpenoids from Sideritis arguta
(Amer Chemical Soc, 2009)
The petroleum ether and acetone extracts of the aerial parts of Sideritis arguta afforded two new and six known diterpenoids with the ent-kaurane skeleton. The structures of the new diterpenoids were determined as ent-7 ...
A biosensor based on graphite epoxy composite electrode for aspartame and ethanol detection
(Elsevier Science Bv, 2006)
A gelatin membrane with carboxyl esterase and alcohol oxidase was subsequently integrated onto the surface of a graphite epoxy composite electrode (GECE). The developed biosensors showed linearity in the range of 2.5-400 ...
Removal of cationic dyes by kaolinite
(Elsevier Science Bv, 2009)
The removal of cationic dyes such as maxilon yellow 4GL (MY 4GL) and maxilon red GIRL (MR GRL) on kaolinite from aqueous solutions has been studied according to the adsorption method. The adsorbed amount of dyes on kaolinite ...
Removal of aniline from aqueous solution by PVC-CDAE ligand-exchanger
(Elsevier Science Bv, 2005)
The adsorption of aniline from aqueous solutions onto cobalt(II)-poly(vinyl chloride)-carboxylated diaminoethane (PVC-CDAE) resin has been studied using a mini-column apparatus at 25 +/- 0.1 degrees C. First of all, ...
Spectrophotochemical and electrochemical characterization of perylene derivatives adsorbed on nanoporous metaloxide films
(Edp Sciences S A, 2007)
Electrochemistry of perylene imide and anhydride derivatives adsorbed on semiconductor TiO2 (NT) and insulator Al2O3 (NA) metal oxide films were presented. Adsorption rates on metal oxide surface are observed to be strongly ...
Comparative studies for the determination of uranyl ion adsorption onto Interpenetrating Polymer Networks (IPNs)
(Springer, 2007)
The adsorption of uranyl ions from aqueous solutions was studied by using three different measurement techniques. Results obtained by gamma-spectrometry, UV-visible spectrophotometry and gravimetry have been compared. It ...
