Activation of Soot Carbon Prepared by Paraffin Candle and its Application as Adsorbent Surface of Some Organic Dyes

Abstract

In this study, locally available and inexpensive materials were used to produce AS₂, which is widely used in adsorption processes. The AS₂ was prepared from thermally treated of AS₁ at temperature 40 ̊C for 2 hours. The properties of AS₂ were identified by FTIR, SEM, BET and XRD technique. The AS₂ was used to adsorb the DR and CV dyes from aqueous solutions and the result show that the AS₂ that prepared from AS₁ is good absorbent. The influence of PH, temperature, Equilibrium time, the adsorbent weight of the adsorption dyes was studied, it was shown that the efficiency of adsorption decreased at PH = 10 and increased at PH=4. The results also showed that the efficiency of adsorption dye on AS₂ decreased by increasing temperature and the optimum contact time of absorption is 15 min. and the optimum adsorbent weight is 0.08 g.
