Abstract

Athi tree leaves (Ficus relegiosa) powder carbon was used as an adsorbent for the removal of DNB-106 dye from an aqueous solution. The studies were carried out under various experimental conditions such as agitation time, dye concentration, adsorption dose, and pH to assess the potentiality of Athi leaves powder carbon (ATC) for the removal of DNB-106 dye from wastewater. A greater percentage of dye removal was observed with decrease in the initial concentration of dye and increase in amount of adsorbent. The adsorption of dye on ATC was found to follow a gradual process. Equilibrium isotherms were analysed by the Langmuir models of adsorption and were applicable with maximum monolayer adsorption capacity of 4.5mgg-1. The dimensionless factor, RL of the DNB-106 dye, ATC isotherm revealed that the adsorption process is favourable in nature.
