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...

The present investigation assesses the application of ceric sulfate for the removal of the colorant reactive blue19 (R.B19) from synthetic wastewater. The adsorption characteristics and dye removal efficiency of adsorbent have been determined by investigating factors such as effect of pH (pHOptimum

In the biorefinery using lignocellulosic biomass as feedstock, pretreatment to breakdown or loosen lignin is important step and various approaches have been conducted. For biological pretreatment, we screened Bacillus subtilis KCTC2023 as a potential lignin-degrading bacterium based on veratryl alcohol (VA) oxidation test and the putative heme-containing dye-decolorizing peroxidase was found in...

The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...
