Activated carbon, prepared from an agricultural waste, cashew nut shell (CNS) was utilized as adsorbent for the removal of methylene blue (MB) dye aqueous solution. Batch adsorption study carried out with variables like pH, dose, initial concentration and time. The response surface methodology (RSM) applied to design experiments, model process optimize variable. A 24 full factorial central composite successfully employed experimental analysis results. parameters concentration, time...
Abstract This paper discusses about the adsorption of metal ions such as Cu(II), Cd(II), Zn(II), and Ni(II) from aqueous solution by sulfuric acid treated cashew nut shell (STCNS). The process depends on pH, adsorbent dose, contact time, initial concentration, temperature. kinetics was relatively fast equilibrium reached at 30 min. follows Langmuir isotherm model. maximum capacity values modified (CNS) for were 406.6 mg/g 436.7 455.7 456.3 Ni(II). thermodynamic study shows onto STCNS...
In this study, sulphuric acid treated cashew nut shell (STCNS) was used as adsorbent for the removal of lead(II) ions from aqueous solutions. Adsorption studies were performed by varying solution pH, contact time, and temperature. Experimental data analyzed model equations such Langmuir, Freundlich, Temkin, Dubinin-Radushkevich isotherms it found that Freundlich isotherm fits best with experimental at different temperatures studied. The maximum adsorption capacity on STCNS determined 408.6,...
Abstract Cashew nut shell (CNS) is an agricultural waste was investigated as a new adsorbent for the removal of zinc(II) from aqueous environment. Effects solution pH, CNS dose, contact time, initial concentration and temperature on efficiency were tested optimum conditions evaluated. The equilibrium data fitted well with Langmuir isotherm model pseudo‐second‐order kinetic model. monolayer adsorption capacity examined 24.98 mg/g. Changes in standard Gibbs free energy (▵ G °), enthalpy H °)...
In this work, porous chitosan (CS) was investigated as a biosorbent for the removal of iron (II) from synthetic fracking wastewater. The underlying problem with production water industries is that it contains up to 55 mg/L, which needs be eliminated. Porous CS had specific surface area 1.05 m 2 /g average pore diameter 319 A, determined by using Brunauer‐Emmett‐Teller analysis. kinetics, isotherms, and thermodynamic analysis confirm can potential candidate removal. Both pseudo‐first‐order...
Abstract BACKGROUND The effects of byproducts lignocellulosic hydrolyzates, such as furfural, 5‐hydroxy methyl furfural ( HMF ), vanillin, para‐hydroxy benzaldehyde PHB and syringaldehyde, on the growth lipid accumulation by Lipomyces starkeyi were investigated. All studies conducted using a minimal medium. RESULTS patterns individual sugars (glucose xylose) similar, sequential utilization was observed when both present in tolerance to acid‐hydrolysis byproducts, promising. CONCLUSION...
Microbial fermentation processes are of great importance for the production many bioproducts.Even established processes, improvements in product yield, productivity, and quality always continually demanded.This is particularly true as products mature from being novelty to high demand, even bulk, substances, has been witnessed several antimicrobial compounds.High-density cultivations have found very useful producing a large number modern bioproducts.Selection mode fermentation, operating...
