In the present study we explore the possibility of deploying agricultural waste such as Coirpith and Peanut shell waste as heavy metal (lead) adsorbents from a synthetic media. The adsorption of lead (Pb) was carried out using Response Surface Methodology (RSM). The influence of adsorption factors viz., initial concentration of adsorbate (Pb), adsorbent dosage, and agitation time (Exposure time of adsorbate). A total of 15 runs of experiments were conducted employing the detailed conditions designed by RSM based on Box-Behnken Design. Results as Contour plots and Surface plots were analysed to know the interactions between the factors. Coirpith could absorb a maximum of 99.060% whereas, a maximum adsorption of 96.27% was achieved by peanut shell. The experimental values well agreed with the RSM predicted values. Coirpith seems to be better adsorbent over peanut shell. RSM seems to be an ideal tool to undertake adsorption, bio-remedial studies.
In the present study we made an effort to deploy orange peel as adsorbent to remove Congo red dye from a synthetic media. Adsorption of Congo red dye was carried out using Response Surface Methodology (RSM).The influence of various factors such as adsorbent dosage, initial concentration of adsorbate and agitation time on adsorption was analyzed. A total no of 13 runs of experiments were conducted by using the detailed conditions which is designed by RSM based Box-Behnken Design. Contour plots and surface plots were analyzed to know the effect of factors. Activated orange peel could adsorb a maximum of 96.776% of congo red dye. The values observed in the experiment well agreed with the RSM predicted values .Activated orange peel seems to be better adsorbent and RSM could be a great tool undertake adsorption.: Congo Red Dye, Adsorption, Response Surface Methodology, Orange Peel, Box-Behnken Design.In the present study we made an effort to deploy orange peel as adsorbent to remove Congo red dye from a synthetic media.
