The different source of wastewater from 400 industries disposes their wastewater directly to the Citarum River, which is predominantly dominated by the textile industry. Those industrial activities generate hazardous heavy metals such as Cr(VI) which can degrade the quality of the river. In this research, we will conduct a treatment on series of Cr(VI) containing surface water to meet the drinking standard of raw water. Zeolite-FeO is synthesized from natural zeolite in Sukabumi, and then impregnated with FeO, characterized using XRD and the result shows that iron oxide precisely hematite (α-Fe2O3) successfully impregnated into the zeolite. The Zeolite-FeO then modified with sucrose to give positively charged on the surface by the contribution of carbon. The adsorption process is carried out in batch with artificial waste containing Cr2O7 2- to obtain the optimum conditions such as the effect of time, pH and initial concentrations. From the adsorption experiment, the result shows the highest efficiency removal is 70,72% at pH 2 for 45 minutes by Zeolite-FeO-Sucrose.[/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 experiment,Adsorption process,Hazardous heavy metals,Hexavalent chromium,Industrial activities,Initial concentration,Optimum conditions,Positively charged[/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][/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][/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/10.1088/1757-899X/536/1/012067[/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]
