Phenol is one of the water pollutants subsequently released into the waste water in manufacturing papers, paints, textile and plastics. Phenol causes serious health effect if in contact with human hence removal of this substance from waste water is crucial. Using bio sorbent in adsorption of phenol offered a green and cheap method for phenol removal particularly in Bandung area where supply of bio sorbent from agricultural waste are abundant. Biomass from Chinese cabbage (Brassica Pekinensis L.) contains cellulose, hemicellulose and lignin, among other substances that present in smaller amount. Dried stems were blended and filtered through 140 mesh and washed with ethanol to provide biosorbent. Modification was carried out by treatment with epichlorohydrin and HCl. Biosorbents were characterized using FTIR, SEM and BET analysis. Adsorption study was carried out according to the following parameters: pH range 5-9, contact time 10-80 minutes, mass of biosorbent 0.2-1.1 g and initial concentration of phenol is 10-50 mg/L. Upon adsorption, the concentration of phenol was measured by HPLC analysis at the following parameter: eluent methanol: water 7:3 v/v, flowrate 0.8 mL/minute at 273 nm. Untreated biosorbent showed adsorption capacity 0.097 mg/g whilst treatment with epichlorohydrine and HCl showed a decrease in adsorption capacity of 0.057 mg/g and 0.059 mg/g respectively. The optimum adsorption capacity was obtained at pH 8, 20 minutes contact time, 0.8 g mass of biosorbent and initial phenol concentration of 10 mg/L.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Adsorption capacities,Adsorption of phenol,Adsorption studies,Brassica,Epichlorohydrine,Initial concentration,Manufacturing process,Phenol concentration[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Adsorption,Brassica Pekinensis L,Epichlorohydrine,Phenol[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We would like to express our gratitude to Ministry of Research and Higher Education (RISTEKDIKTI) for generous funding for this research.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.4028/www.scientific.net/KEM.811.71[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
