Modelling and analysis on the removal of methylene blue dye from aqueous solution using physically/chemically modified Ceiba pentandra seeds

In this research, batch adsorptions of methylene blue (MB) dye using physically and chemically activated Ceiba pentandra seeds (PACP and CACP) have been inspected. SEM-EDAX and XRD analysis for adsorbents have been studied. The acquired consequences of isotherm and kinetic investigations exhibit that Freundlich and pseudo-first order models demonstrated better association. Langmuir adsorption capacity of PACP and CACP was observed as 324.01 and 469.4 mg/g, respectively. Sticking probability for MB dye was found to be high. This adsorption process was unconstrained and exothermic in nature. This modified materials has an ability to remove MB dye from polluted water.
