The microwave-assisted synthesis and characterization of novel, octakis(2-hydroxyethoxy)resorcinarene bridged polymeric metallophthalocyanines
(Elsevier, 2009)
The new metallophthalocyanine (Zn, Cu, Ni, Co) polymers containing 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)-2,8,14,20-tetramethylresorcinarene are described. Firstly, 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)- ...
Synthesis of 1,2,4-Triazole derivatives and determination of protonation constant
(2009)
A microwave irradiation method has been developed for the synhesis of some 1,2,4-triazole derivatives using environmentally benign solvent ethanol in open vessels. Twelve 1,2,4-triazole derivatives were synthesized in good ...
Determination of adsorptive properties of a Turkish Sepiolite for removal of Reactive Blue 15 anionic dye from aqueous solutions
(Elsevier, 2009)
Reactive Blue 15 (RB 15) adsorption on the Turkish Sepiolite was carried out by batch equilibrium technique. IR spectrum and surface area measurement of the composite of dye-sepiolite (Turkish) pointed out that dye species ...
Reversible immobilization of catalase by using a novel bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents
(Elsevier, 2008)
This study focused on developing bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents (38-105 ?m) for catalase adsorption from aqueous solutions. Pseudo-biospecific affinity ligand l-cysteine was covalently binded ...
3-Ethyl-4-(p-chlorobenzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-one (EPHBAT) as precipitant for carrier element free coprecipitation and speciation of chromium(III) and chromium(VI)
(Elsevier, 2009)
A method for the separation and speciative determination of Cr(VI) and Cr(III) has been developed. The procedure is based on coprecipitation of Cr(III) on 3-ethyl-4-(p-chlorobenzylidenamino-4,5-dihydro-1H-1,2,4-triazol-5-one ...
