Adsorption Studies for Arsenic Removal Using ActivatedMoringa oleifera

[摘要] A new low cost adsorbent, activatedMoringa oleiferahas been developed for aqueous arsenic removal. Batch experiments were revealed that As removal was up to 71.3% using activatedMoringa oleifera. Kinetics studies revealed that Langmuir isotherm was followed with a better correlation than the Freundlich isotherm. The thermodynamic parameters such asΔH,ΔS, andΔGwere computed from the experimental data. These values show that the adsorption is endothermic and spontaneous in nature. Thus, this recently developed cost-effective novel biosorbent, activatedMoringa oleiferacan be used as household level to mitigate the arsenic problem.
