| description | The capacity of carbon monolith for pesticide removal from water, and the
mechanism of pesticide interaction with 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 in pesticide adsorption, carbon monolith surface was functionalized by
chemical treatment in HNO3, H2O2 and KOH. The surface properties of the
obtained samples were investigated by BET surface area, pore size
distribution and temperature-programmed desorption. Adsorption of pesticides
from aqueous solution onto activated carbon monolith samples was studied by
using five pesticides belonging to different chemical groups (acetamiprid,
dimethoate, nicosulfuron, carbofuran and atrazine). Presented results show
that higher temperature of carbonization and the amount of activating agent
allow obtaining microporous carbon monolith with higher amount of surface
functional groups. Adsorption properties of the activated carbon monolith
were more readily affected by the amount of the surface functional groups
than by specific surface area. Results obtained by carbon monolith
functionalisation showed that π-π interactions were the main force for
adsorption of pesticides with aromatic structure, while acidic groups play an
important role in adsorption of pesticides with no aromatic ring in the
chemical structure. |
