Abstract: This study demonstrated that activated carbon from waste PET bottle, could be used as an effective adsorbent for the removal of SMX and CBZ. Four adsorbents from waste PET bottle were experimented to remove SMX and CBZ from aqueous solution. The effects of various factors, such as the initial adsorbate concentration, temperature effect and contact time were investigated in series of experiments. To determine the effect of activation agent contents on SMX and CBZ adsorption, 1000 mg/l of SMX and CBZ was studied taking into account an initial concentration. The amount of each of the activated carbons used is 0.150 g and the shaking time used is 72 hours. The results of the adsorption tests showed the effectiveness of all adsorbents used for the elimination of the two PPCPS materials used. According to the removal capacity results of the 4 activated carbons used on the adsorption of SMX and CBZ, it seems that the activated carbon 1/4 with composite with (Coal=1 and KOH=4) gave the highest adsorption quantity (251.12 mg/g and 250.195 mg/g, respectively for SMX and CBZ) followed by activated carbon 2/4 with composite with (Coal=2 and KOH=4) gave (241.37 mg/g and 248.77 mg/g, respectively for SMX and CBZ). On the other side the lowest adsorption capacity of 4/4 gave (194.17 mg/g and 240.301 mg/g, respectively for SMX and CBZ) were recorded for (Coal=4 and KOH=4). The pseudo-second order model and Langmuir isotherm showed a better description of experimental adsorption data for SMX and CBZ than others models used.
