Activated carbon derived from tea waste: A promising supporting material for metal nanoparticles used as catalysts in hydrolysis of ammonia borane
(Pergamon-Elsevier Science Ltd, 2020)
Activated carbons with high porosity and high surface area are promising materials to be used in wide-range applications. They can easily be prepared from various biomass source following by simple and reproducible activation ...
Recycling of an agricultural bio-waste as a novel cellulose aerogel: A green chemistry study
(Springer, 2020)
Cellulose aerogel (CA) isolated from tea stem wastes (TSW) is a good fire retardant and heat insulator, environmentally friendly, thermally stable and highly porous material with a network structure. These outstanding ...
Newly synthesized bentonite-histidine (Bent-His) micro-composite affinity sorbents for IgG adsorption
(Elsevier, 2007)
Bentonite has several advantages for use as a support, including its lack of toxicity, chemical reactivity and hydrophilicity allowing easy fixation of biomolecules. A new approach was developed to obtain an efficient and ...
Characterization and pillaring of a Turkish bentonite (Resadiye)
(Elsevier, 2007)
The shifts of the Si{single bond}O{single bond}Si stretching and the Si{single bond}O{single bond}Al and Si{single bond}O{single bond}Si bending modes, as well as the free silica peak in the IR spectra and the strengthening ...
Performance of magnesium oxide-coated bentonite in removal process of copper ions from aqueous solution
(Elsevier, 2010)
This paper presents the adsorption of Cu(II) ions from aqueous solution on modified Unye bentonite. Adsorption of Cu(II) ions by magnesium oxide-coated bentonite (MCB) sample was investigated as a function of the initial ...
Structural analysis of reactive dye species retained by the basic alumina surface
(2009)
The alumina-dye composites were prepared by treating the basic alumina with the water solutions of Reactive Red 120 (RR 120) and Reactive Blue 15 (RB 15) dyes. The bands of low intensities in the 1400-1600 cm-1 region and ...
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 ...
Adsorption of Reactive Red 120 from aqueous solutions by cetylpyridinium-bentonite
(Wiley, 2010)
BACKGROUND: The removal of Reactive Red 120 (RR 120) from aqueous solutions using cetylpyridinium modified Resadiye bentonite (CP-bentonite) prepared by ion exchange was investigated with particular reference to the effects ...
Radiological and chemical assessment of phosphate rocks in some countries
(Elsevier, 2010)
In this study, the radiological, structural and chemical characterizations of Mardin-Mazi{dotless}da?i{dotless} phosphate rock, which is an important phosphate fertilizer source in Turkey were investigated and compared to ...
