MB decolarization with pure TiO 2 and Ag doped TiO 2 based photocatalytic system were investigated under UV-A and UV-Visible conditions. Different ratios of Ag were used as metal dopant. 1% Ag-TiO 2 increased the decolorization efficiencies of MB and MO dyes, also the k app constant enhanced under...

Biosorption is an emerging technique for water treatment utilizing abundantly available biomaterials.The potential feasibility of magnetic peanut hulls particle for removal of cationic dye (methylene blue) from aqueous solution was investigated. The effects of various experimental parameters were...

Low cost agricultural waste adsorbents can be viable alternatives to activated carbon for the treatment of contaminated wastewater. Sugarcane Bagasse, an abundant agriculture waste in Egypt, was used in the present study to prepare activated carbon. Batch adsorption experiments were conducted to...

The present study investigates the ability of formaldehyde treated Simarouba glauca seed shell powder for removal of methylene blue (MB) from aqueous solutions. Batch adsorption studies were carried out under various experimental conditions such as agitation time, dye concentration, adsorbent dose...

Cu 2O photocatalyst is synthesized by solvothermal method. Morphology and structure of Cu 2O photocatalyst are analyzed by SEM, XRD and N 2 sorption technique. The catalytic performances and reaction kinetics of Cu 2O photocatalyst for the degradation of methylene blue (MB) are investigated. The...

The purpose of the present work is to test the possibility of using the spent tea dust and raw coir pith for the removal of methylene blue (MB) from aqueous solution. The effects of the contact time, adsorbent dosage and solution pH were studied in batch experiments at 27 °C. Results showed that a...

Laboratory studies reported earlier, have shown very promising results in the selective removal of dyes from aqueous solutions by a commercially available (super absorbent polymer) SAP, Jalshakti® (JS). JS is mesoporous in nature and is a potential adsorbent for the basic dyes studied. This paper...

Water hyacinth Eichhornia crassipes was found to have biosorption capacity for cationic dyes, malachite green and methylene blue from aqueous solutions. To evaluate the biosorption capacity and characteristics, the effect of solution pH, initial dye concentration, temperature, dose of biosorbent...

The removal of dyes from colored effluents, particularly from textile industries, is one of the major environmental concerns these days. Current methods for removing dyes from wastewaters are costly and cannot effectively be used to treat wide range of such wastewaters. This work describes the use...

The mechanism of Methylene Blue adsorption on biosolid (waste sludge) has been studied through batch experiments. The effects of various experimental parameters, such as pH (3- 11), biosolid dosage (1-10 g l-1), contact time (5-1440 min) and initial dye concentration were investigated. The results...
