Biochar: a low-cost adsorbent of Methylene Blue from aqueous solutions

Abstract 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 biocarbons variable parameters (initial biochar concentrations, temperature, pH solution). The experimental data have been computed using Freundlich isotherms. percentage onto shown correlate linearly with adsorbent quantity concentration, MB-biochar contact time pH. results process are well correlated model: R 2 > 0.989 for 0.977 biomass-biochar. Biocarbons be an effective low-cost material removal dye colourisation solution.
