Removal of trivalent arsenic from contaminated groundwater was studied using steam activated carbon prepared from the leaf, seed and pod of Moringa oleifera (MO) plant of the indigenous-cultivar of Bangladesh. Batch adsorption experiments were performed as a function of contact time, adsorbent doses and variants. The removal efficiency of the MO-leaf-carbon and MO-seed-carbon was substantial, while it was trivial for MO-pod-carbon. The pseudo-first- and second-order and intra-particle diffusion equations were used to evaluate the sorption mechanism of the MO carbon options. The MO is a common plant variety of the arsenic-affected Bengal delta. Therefore, it can be exploited as a cheaper resource of carbonaceous adsorbent for the economical removal of arsenic from the water.

Abstract
Removal of trivalent arsenic from contaminated groundwater was studied using steam activated carbon prepared from the leaf, seed and pod of Moringa oleifera (MO) plant of the indigenous-cultivar of Bangladesh. Batch adsorption experiments were performed as a function of contact time, adsorbent doses and variants. The removal efficiency of the MO-leaf-carbon and MO-seed-carbon was substantial, while it was trivial for MO-pod-carbon. The pseudo-first- and second-order and intra-particle diffusion equations were used to evaluate the sorption mechanism of the MO carbon options. The MO is a common plant variety of the arsenic-affected Bengal delta. Therefore, it can be exploited as a cheaper resource of carbonaceous adsorbent for the economical removal of arsenic from the water.
