Utilization of Low-Cost Bio-waste Adsorbent for Methylene Blue Dye Removal from Aqueous Solutions and Optimization of Process Variables by Response Surface Methodology Approach
TL;DR: In this paper, the sesame seed cake was utilized as an adsorbent to remove methylene blue which is one of the most used cationic dyes in various industries. But the results obtained from the adsorption experiments were evaluated by using an analysis of variance, and the statistically significant quadratic model was developed.

Biochar: a low-cost adsorbent of Methylene Blue from aqueous solutions
Justyna Kujawska,H. Wasag +1 more
TL;DR: In this article, the removal of methylene blue (MB) from aqueous solutions by compost-biochar and plant biomass biochar mixtures is investigated under batch conditions to determine the adsorption capacity of biocarbons under variable parameters (initial MB and biochar concentrations, temperature, pH of the solution) The experimental data have been computed using Freundlich adsorptions isotherms.

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.

Use of cellulose-based wastes for adsorption of dyes from aqueous solutions.
TL;DR: Based on the adsorption capacity, it was shown that banana peel was more effective than orange peel and intraparticle diffusion of dyes within the particle was identified to be rate limiting.
