Abstract

Effect of microalgal pyrolytic bio-char on the copper ions removal from water was investigated. Scanning Electron Microscope (SEM) and elemental analysis were done for bio-char before the adsorption experiments. Adsorbent dosage (10-40 g L-1), copper concentration (10 000-20 000 mg L-1), time (15-90 min) parameters were changed. UV visible spectrometer was used to analyze the results. The most adjustible kinetic and adsorption model with data were specified as Pseudo-Second-Order and Freundlich respectively. Maximum adsorption capacity and removal efficiency were found as nearly 150 mg Cu(II) g-1 bio-char and 20% respectively.To characterize the char after the adsorption, it was took the advantage of fouirer transform infrared spectrophotometer (FTIR).
