title: Utilization of rice-husk and coconut shell carbons for water disinfection.
abstract: In the present study, experiments were conducted to investigate the feasibility of using carbon derived from rice husk and coconut shell for the decontamination of water containing Escherichia coli (E. coli). The effects of silver impregnation on these agro-waste carbons were also investigated. All the carbons showed >99% removal of E coli. Among the four carbons studied, rice husk based carbon (RHC) showed better removal than the other carbons investigated. However, silver impregnated carbons showed only marginal increase in the decontamination experiments. SEM and BET results reveal that the carbons were mesoporous in nature. FTIR shows the presence of functional groups viz. C=O and -OH that might be responsible.for adsorption of E. coli on the carbon.
