Abstract In recent years, numerous investigations have explored the use of biochar for removal organic and inorganic pollutants in single component systems. Biochar is a carbonaceous material produced from waste biomass, mainly by thermochemical conversion methods. This was used as biosorbent various processes pollutants, its efficiency strongly influenced characteristics biomass feedstock. review integrates works literature to understand biosorption behaviour dyes onto biochar-based...

The removal of a Basic Blue 41 (BB41) and Red 09 (BR09) from an aqueous solution by biochar derived Arachis hypogaea shell (Groundnut shell) was studied.The sorption cationic dyes (BB41 BR09) studied varying dosage (1-10 g/L), pH (3-10), temperature (30 to 50 °C), contact time (0-360 min) initial dye concentration (25-200 mg/L).At optimum dosages 2 g/L 1 (BR09), (8), (50 mg/L), equilibrium (240 min), groundnut recorded BB41 BR09 uptakes 22.322 40.655 mg/g.The kinetic research confirmed that...

In the present study, bioremediation of Basic Violet 03 is examined using biochar derived from agricultural wastes. The pyrolytic studies revealed that ideal temperature for maximum yield Coconut Shell (CSB), Ground nut (GnSB) and Rice Husk (RHB) was obtained as 400 °C, 350 °C 300 respectively. Further batch mode operations, it concluded optimum conditions dose, pH, initial concentration are 4 g/L, 8, 40 75 mg/L with a uptake 15.79 mg/g, 17.28 12.64 mg/g CSB, GnSB RHB. adsorption isotherm...

In this work, the preliminary batch trials were performed to optimize factors influencing Remazol dyes remediation using Ulva reticulate biochar.U. a green marine seaweed is used as low-cost adsorbent remediate in aqueous solution.The optimum values achieved at 2 g/L biochar dosage, 2.0 equilibrium pH, 0.05 mmol/L initial dye concentration, and 30°C temperature with maximum removal efficiency of around 92%. Thermodynamic studies proved that reactions are spontaneous endothermic.Toth...

Abstract The main goal of this research was to prepare composts from neem ( Azadirachta indica A. Juss) leaves and water hyacinth plant for the remediation Basic Blue 41 (BB41) bearing wastewaters. process composting performed using Effective Microorganisms (EM) tree EM LC ) waste WHC ). Through preliminary experiments, biosorption BB41, 1.18 mm 2 g/L were identified as optimum particle size compost dosage, respectively. pH edge experiments revealed that 8 BB41 isotherm indicated can biosorb...

The current study evaluates the adsorption capacity of Cocos Nucifera (Coconut) shell derived biochar for basic dyes Basic Blue 41 (BB41) & Red 09 (BR09) from aqueous solution. experiments proved that 80% dye removal was attained in optimal operating conditions (adsorbent dosage 4 g/L, pH 8, temperature 35°C, 50 mg/L initial concentration). Four different isotherm models were used to derive best fit model, based on values correlation coefficient and % error BB41 sorption revealed Toth model...

The present research compares the prediction of response surface methodology (RSM) and artificial neural network (ANN) on decolorization Reactive Orange 16 (RO16) using a novel adsorbent produced from Ulva lactuca (seaweed).These mathematical models were designed based four process conditions biochar dose, pH, temperature, initial concentration.The experimental trials concluded that dye removal 93.10% was achieved at an optimum dosage 2 g/L, pH 2, concentration 0.5 mmol/L, temperature...

Marine seaweed is considered as one of the efficient tools for mitigation carbon dioxide and it naturally overgrown in India. Biochar produced from seaweeds will remediate toxic pollutants present soil wastewater. The current investigation examined potential biochar synthesized Ulva reticulata decolorization Remazol Brilliant Orange 3 R (RBO3R). An up-flow-packed bed column designed to check feasibility effluent treatment a real wastewater system. partition coefficient was calculated...

The current experimental work was designed to explore the maximum biosorption efficiency of biochar derived from agricultural waste groundnut shell (GnSB) for removal Basic Violet 03 (BV03) dye aqueous solution.To validate and optimize interactions among different parameters (pH, dosage, temperature, initial concentration contact time) BV03 in solution, Box-Behnken design (BBD) model response surface methodology employed.Forty-six base run carried out with six center points.The values F P...

The current research paper is focused on investigating the influence of Laser beam machining process parameters surface roughness and kerf width HSLA steel. Taguchi’s L 18 orthogonal array adopted to conduct studies. MOORA method used evaluate suitable combination LBM parameters. combined effect performance measures analysed using analysis variance identify significance result. Consequently, responses were explored. morphology machined optimal set has been studied.

The release of textile effluents into the biosphere is a serious threat to environment and promotes several health issues.Although studies have been carried out in remediation using adsorbents, continuous mode operation (packed bed) treat effluent generated from cotton-based industry biosorbent seldom reported.Here, one such investigation made remediate Remazol solution batch operation.A maximum decolourization efficiency 77.5% 49.66% was obtained for Ulva lactuca derived biochar...
