ABSTRACT:
A simple and eco-friendly procedure for removal of sodium do-decyl sulphate (SDS), an anionic surfactant (AS) from waste water has been discussed in the present research paper. The paper investigates the usability of activated charcoal for removal of SDS from aqueous solution. Studies have been reported on adsorption of SDS on carbonized, untreated and treated sweet lime peel charcoal (SLPC). Ability of activated SLPC, removal of SDS and study of adsorption isotherms are skilled by pH, conductivity and surface tension methods. The analytical procedure is followed for the determination of pH, conductivity and surface tension. Results of the study demonstrated usability of activated charcoal as a promising adsorbent in surfactant adsorption. The method has been applied to determine the AS in water samples with satisfactory results. Experiments have executed by altering dosages of adsorbent bed and adsorption behavior is analyzed with Freundlich and Langmuir adsorption isotherms. The R2 values of Freundlich adsorption isotherm for pH and conductivity are 0.9623 and 0.9671 respectively. Similarly R2 values of Langmuir adsorption isotherm for pH and conductivity are 0.9746 and 0.9680 respectively.
