Abstract

  Batch experiments were carried out for the adsorption of Janus Green B (JGB) onto walnut kernel shell particle. walnut kernel shell treated with burn in 300 C0 was tested as a low cost adsorbent for the removal of Janus Green B from aqueous solution . The effects of various experimental parameters, such as adsorbent dosage and particle size, initial dye concentration, pH and contact time,  were investigated in batch mode . An amount of 1.5 g/l of (WKSC)  could remove 99.36 % of the dye from an aqueous solution of 50 ppm with the agitation time 150 min and particle size 75 mm and  with acid medium (pH=2) . The well Known Langmuir and Freundlich isotherm models were applied for the equilibrium adsorption data and the various isotherm parameters were evaluated. The results indicate that activated walnut kernel shell carbon (WKSC) could be employed as a low cost alternative to commercial activated carbon in wastewater treatment for the removal of color and dyes .
