In this study, the ability of immobilized ceramic/ZnO nanoparticles (NPs) for decolorization of Reactive black 5 dyes was investigated. A laboratory scale of rotating disc type reactor with UV-C lamp and dip coating method to immobilize nanoparticles were used in this study. Ceramic/ZnO NPs were then characterized by SEM-EDS. EDS result has shown that 82% of ZnO NPs were dispersed on the ceramic surface with maximum catalyst dosage of 5.5 mg/cm2. It was achieved after 3 cycles of impregnation process at 500°C. Photocatalytic activity of ceramic/ZnO NPs was strongly depended on pH and RB5 initial concentration. It possesses the highest photocatalytic activity (100% of decolorization efficiency) at the extreme alkaline condition and low RB5 concentration (3 mg/L) after 90 min of treatment time.[/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]Alkaline conditions,Dipcoating methods,Impregnation process,Initial concentration,Inorganic salts,Nanoparticle (NPs),Reactive black 5 dyes,Textile wastewater[/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]This study was performed within the ITB-P3MI research scheme; a research program on community service and ITB innovation research group which is co-funded by the Ministry of Research, Technology and Higher Education, Indonesia (Ristek-Dikti).
