ADSORPTION OF TRIHALOMETHANES ON ACTIVATED LIGNITE
Abstract
All materials which are rich in carbon content could be used after activation or adsorption. These materials include coal, lignite, wood, Boone, coconut shells, nut shells, rice husks, and various fruits seeds. Activated carbons obtained from these materials are usually hard and dense. Therefore they could be used in water treatment for long time without deterioration. Activated carbons used in controlling environmental pollution should have high surface area and porosity. Activated carbon is obtained by the process of carbonization fallowed by activation of the initially carbonaceous material. The product of the carbonization process, i.e. of pyrolysis of the carbon containing material, conducted in the absence of air and any chemicals, is a material virtually inactive with regards to adsorption, with a specific surface area of several m2/g. The aim of this work is to investigate Trihalomethanes adsorption capacity of the natural lignite found around Konya. Activated carbon from Ermenek lignite were produced using modified method. The combination of the factors, namely KOH dosage, and the HCl washing enhanced significantly the sorbent activity. Removal of, \%97 for Chloroform , \%97 for Bromodichloromethane , \%98 for Dibromochloromethane, \%98 for Bromoform were achived by the use of Ermenek activated carbon.
