Influence of different carbon monolith preparation parameters on pesticide adsorption
Апстракт
The capacity of carbon monolith for pesticide removal from water, and the mechanism of pesticide interaction with the carbon surface were examined. Different carbon monolith samples were obtained by varying the carbonization and activation parameters. In order to examine the role of surface oxygen groups on pesticide adsorption, the carbon monolith surface was functionalized by chemical treatment in HNO3, H2O2 and KOH. The surface properties of the obtained samples were investigated by determination of the Brunauer, Emmett and Teller (BET) surface area, pore size distribution and temperature-programmed desorption. Adsorption of pesticides from aqueous solution onto the activated carbon monolith samples was studied using five pesticides belonging to different chemical groups (acetamiprid, dimethoate, nicosulfuron, carbofuran and atrazine). The presented results show that higher temperature of carbonization and amount of activating agent enable microporous carbon monolith with higher num...bers of surface functional groups to be obtained. The adsorption properties of the activated carbon monolith were more readily affected by the number of surface functional groups than by the specific surface area. Results obtained after carbon monolith functionalization showed that pi-pi interactions were the driving main force for adsorption of pesticides with an aromatic structure, while acidic groups played an important role in adsorption of pesticides with no aromatic ring in their chemical structure.
