Therefore, nowadays more focus has been given for the use of agricultural waste as low cost adsorbents for the removal of heavy metals from waste water. In this paper, the studies on removal of Cu (II) from waste water on borasus flabellifer coir powder as adsorbent were investigated in a batch mode experiments. The agitation time, the adsorbent size, adsorbent dosage, initial copper concentration, and the effect of solution pH have been studied. The Freundlich model for Cu (II) adsorption onto borasus flabellifer coir powder was proved to be the best fit followed by Langmuir model and Tempkin model based on high regression coefficient R2 value. The adsorption kinetic behavior was best described by second order. The maximum percentage removal of metal efficiency was found to be 97.92 %. The results obtained in this study illustrate that borasus flabellifer coir powder is expected to be an effective and economically viable adsorbent for Cu (II) removal from industrial waste water.
