The sorption of three disperse dyes, namely, Disperse Blue 56 (DB56), Disperse Red 74 (DR74) and Disperse Yellow 119 (DY119), onto alunite has been studied in terms of pseudo-first- and second-order sorptions and intraparticle ...

The biosorption of Cu(II) from aqueous solutions by mimosa tannin resin (MTR) was investigated as a function of particle size, initial pH, contact time and initial metal ion concentration. The aim of this study was to ...

Protease and lipase were purified from sunflower seeds by frequent purification steps with molecular weights of 72.90 kDa and 27.50 kDa, respectively. The purified lipase and protease were immobilized on various carriers ...

ZnO nanoplates were synthesized by microwave-hydrothermal methods. Pd doped ZnO photocatalysts were prepared by microwave irradiation, UV irradiation, and borohydride reduction methods. The Pd/ZnO photocatalysts were ...

Competitive biosorption of Pb2+,Cu2+ and Zn2+ on valonia tannin resin (VTR) present in binary and ternary mixture were compared with the single metal solution. The effects of the presence of one metal ion on the biosorption ...

The immobilization method consists of the production magnetite nanoparticles (Fe3O4) by solvothermal treatment of FeCl3 and sodium acetate (NaAc) in the presence of ethylene glycol. Subsequently, the surface of magnetite ...

The removal of color from synthetic wastewater containing a reactive dye, C.I. reactive red 124, was experimentally investigated using direct current (D.C.) electrocoagulation (EC). In the EC of the reactive dye the effects ...

For evaluating the tannin (natural polyelectrolyte) and AN913 (synthetic anionic polyelectrolyte) as a coagulant aid For treating raw water to remove suspended matter the tannin or AN913 was added to the synthetic water ...

Immobilized enzymes are significantly studied both environmental and textile industries. In this work, glucose oxidase was immobilized on the tannin coated NiFe2O4 magnetic nanoparticles for decolorization of indigo carmin. ...

The cyclic voltammetry studies indicated that the HOMO and LUMO energy levels of three sensitized metallophthalocyanines could ensure efficient electron injection and thermodynamically favorable dye regeneration. The ...
