Response Surface Modelling of Methylene Blue Adsorption onto Seaweed, Coconut Shell and Oak Wood Hydrochars

Response Surface Methodology for Optimizing Adsorption Process Parameters of Reactive Blue 21 onto Modified Kaolin

In this research modified Kaolin by Cetyltrimethylammonium bromide is used as an adsorbent for the removal of Reactive Blue 21 from aqueous solutions. Response Surface Methodology was used to study the effect of independent variables, such as Reactive Blue 21 dye concentration (20, 40, 60, 80 and 100 mg/L), time (10, 20, 30, 40 and 50), initial pH (2, 4, 6, 8 and 10) and modified Kaolin dosage ...

Adsorption of Basic Blue 41 from Aqueous Solution onto Coconut Fiber Particles

In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time,...

Adsorption Equilibrium, kinetics and thermodynamics of methylene blue from aqueous solutions using biopolymer oak sawdust composite

Oak sawdust (OSD), furniture industrial waste was chemically treated with 0.1N NaOH to give hydrolyzed oak sawdust (HOSD) which was immobilized on alginate biopolymer. Hydrolyzed oak sawdust composite (HOSDC) was utilized as low-cost adsorbent to remove basic dye (methylene blue, MB) from aqueous solution. HOSD and HOSDC were characterized by using Scanning electron microscope (SEM), thermo gra...

Adsorption and Desorption Kinetics Behaviour of Methylene Blue onto Activated Carbon

In the present work investigations on a potential use of activated carbon for the removal of Methylene Blue (MB) from wastewater are presented. Adsorption kinetics of methylene blue has been studied using reaction-based and diffusion-based models. Three kinetic models, namely, pseudo-first-order, pseudo-second-order and the Elovich are analyzed at the temperature of 298 K for the reaction-based...
