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...
This study presents an investigation into the durability of geopolymer concrete prepared using high calcium fly ash along with alkaline activators when exposed to 2% solution sulfuric acid and 5% magnesium sulphate for up 45 days. The was also assessed by measuring water absorption sorptivity. Ordinary Portland cement as control concrete. grades chosen were M20, M40, M60. used present is combination sodium silicate hydroxide ratio 2.50. molarity fixed 12. test specimens were<mml:math...
The unique property of biochar, synthesized from a green seaweed (Ulva lactuca), to remediate complex Remazol dye bearing wastewater was investigated. Preliminary trials were targeted explore the remediation capacity biochar towards each dyes (Remazol brilliant blue R (RBBR), orange 3R (RBO3R), violet 5R (RBV5R), and Black B (RBB)) in single-solute system. results show that equilibrium pH played vital part with maximum sorption observed at 2.0. isotherm experiments confirmed exhibited high...
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...
The water hyacinth plants are renewable natural biomass, proliferate ubiquitously, and abundant in bodies often posing environmental nuisances. To overcome this problem, a novel approach that utilizes plant has to be arrived. This research work mainly deals with application of low cost, non-conventional, newly developed biomaterial, Effective Microorganisms (EM) based Water Hyacinth Compost as biosorbent for the removal basic dyes from aqueous solution. Biosorption like Methylene Blue (MB),...
Abstract An up‐flow fixed column study was conducted to remediate Remazol Brilliant Orange 3R ( RBO 3R) from contaminated solutions using biochar derived Ulva lactuca biomass. The influences of parameters on dye sorption were studied in detail, which include initial concentration, bed depth, and flow rate. Optimization experiments indicated that maximum uptake 0.114 mmol/g observed at 0.25 mmol/L (initial concentration), 0.3 L/hr (flow rate), 25 cm U. depth). Modeling data performed the...
Abstract In this work, regeneration of Remazol dye loaded biochar produced from three different green marine seaweeds namely U.lactuca , U.reticulata and C.scalpelliformis was studied using elutants as a regenerant. Before the regeneration, remediation remazol dyes were in batch trails U. Lactuca derived is found to best ‐suited for all four with removal efficiency order brilliant orange 3R (91%), followed by blue R (89.6%), violet 5R (84.2%) Black B (77.8%). Further real wastewater also...

In this study, coco-peat was tested for its potential to sorb malachite green (MG) and crystal violet (CV) from aqueous solutions. The pH edge experimental results indicated that biosorption of two cationic dyes increased with increase in maximum obtained at 7. Fourier transform infrared spectrometry confirmed the involvement negatively charged groups removal dyes. Furthermore, scanning electron micrographs were used examine surface morphology coco-peat. equilibrium isotherms determined...
Abstract Organic pollutants, such as dyes released during industrial operations are one of the major reasons for degradation water quality. However, treatment technologies to remediate these high volumes wastewaters often not sufficient. Hence, excess dye wastewater generated is usually discharged without prior treatment. The use adsorbents activated carbon widely employed separate molecules from wastewater. Biochar a popular recent alternative dye‐bearing effluents selectively isolate...
