Abstract

In this study, an important parameter in the chemical activation of sorbents was tested which is the impregnation temperature. For this, the chemical activation of cedar cone (an abundant forest waste in Khenchela forest in Algeria) has been tested. The impregnation temperature was varied from 10 to 40 °C including the ambient temperature while the concentration of the agent activator (HNO3) was kipped constant at 2moleL-1 and the rate of impregnation (IR) was equal to 20. The results show that the cedar cone (CC) has an important advantage that it’s not required to treated it in specific temperature, the ambient temperature give a better performance of sorption of a cationic dye (Rhodamine B). The titrations of functional surface show clearly the increase in total of acid functions.
