Optimized Preparation of activated carbon with high porosities based on puck shells (afrostyrax lepidophyllus) by response surface methodology and physico-chemical characterization

The Supplementary Material contains an in-depht description of handling protocol and tables presenting the experimental data which were used to plot certain curves of this paper. The handly protocol of activated carbon preparation, for the determination of iodine number, of Boehm method and for the pHZPC presents the meticulous details with which the manipulation was carried out and the assumptions used to determine the surface functions of the materials. Supplementary Table 1 give The Experimental design matrix generated by Statgraphics 5 plus software for any experiment of activated carbon preparation, Supplementary Table 2 gives the adsorption and desorption data of Nitrogen obtained for CRP, Supplementary Table 3 gives the adsorption and desorption data of Nitrogen obtained for CRB and Supplementary Table 4 gives The pH values of the filtrate obtained after mixing activated carbon with sodium chloride solutions at different pHinitial.
