Optimal isotherm parameters for phenol adsorption from aqueous solutions onto coconut shell based activated carbon: Error analysis of linear and non-linear methods

摘要

Highlights?Coconut shells based granular activated carbon as a low cost agricultural adsorbent for phenol removal.?Novel approach to identify best suitable equilibrium isotherms for adsorption in batch process.?Optimized characteristic constants representing mechanisms in non-linear isotherms models.?Differential evolution approach as an efficient evolutionary optimization technique for optimal parameters.?Comparison of linear and non-linear methods using error analysis.AbstractRemoval of phenolic pollutants from wastewaters has become mandatory due to stringent environmental regulations and adverse effects on aquatic marine environment. Adsorption process which is most effective process to remove pollutants, hinders its applications in diverse
