Microcrystalline cellulose (MCC) was prepared from sugarcane bagasse (SCB) after alkali extraction with sodium hydroxide (NaOH). The MCC treated methylene blue solution. Batch experiments were performed to investigate the effect of contact time, initial dye concentration, pH and adsorbent dosage on adsorption. result shows that adsorption onto influenced by dose, time values. For higher removal...

the photocatalytic activity of nano-bi2o3 was evaluated in degradation of rhodamine b (rhb) as a model of dye pollutant from waste waters. nano sized bi2o3 was synthesized using the chemical precipitation method. the as-prepared sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infrared spectrometry (ft-ir). structural analysis reveale...

Traditional dyeing usually consumes a significant amount of water and salts, thus causing environmental pollution. Salt-free low-water has become an important research direction in the cotton fabric industry. The non-aqueous media technology, using decamethylcyclopentasiloxane (D5) as medium, achieved energy saving emission reduction this To investigate influence inorganic salts on properties r...

Bismuth ferrite, BiFeO3 (BFO) prepared via a coprecipitation method, was used as an effective photocatalyst for the degradation of methylene blue (MB) using white light-emitting diode (LED-50 W) lamp. The as-prepared material characterized by TGA, XRD, SEM-EDX, FTIR, and UV-vis-DRS techniques. effects experimental key parameters such pH, catalyst dosage, initial dye concentration, calcination t...

Dye is one of the waste waters, which will be a problem if content excessive in water. Modifying bentonite with titanium dioxide (TiO2) as photocatalyst for removal dye waste. In this study, composite synthesis was carried out by mixing and TiO2 suspensions. The mass 20 g, variations are 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%. resulting heated using furnace at 550°C 5 hours. Bentonit...

low-cost grapefruit peel (agricultural waste) was used for removal of reactive blue19 dye fromaqueous solutions. the process was studied as a function of contact time, initial dye concentration andph. adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg l-1. an acidic medium was the optimum condition for adsorption of dye at roomte...
