Abstract
Adsorption of heavy metals onto nanoclay was studied using techniques of batch adsorption. The aim of this study was to investigate the adsorption potential of low cost adsorbent paddy field clay for removing heavy metals from effluents. To better understand the property relationship of the adsorption process, the paddy field clay was thoroughly defined by XRD, particle size and zeta potential. The effect of contact time, pH, and adsorbent dose has been studied on the adsorption mechanism. Results showed that the adsorption rate initially increased rapidly and the optimal efficiency of removal was achieved in about 45 minutes. Further increase in contact time showed no noticeable change in the equilibrium concentration; that is, the process of adsorption had reached equilibrium. The adsorption was favoured with maximum adsorption at pH10.0. The adsorption isotherms could be fitted well by the Langmuir model. Thus, the results consider that Nanoclay has considerable potential as physical, safe and efficient aqueous solution adsorbent materials for NH4+ adsorption.
