In this work, a ceramic membrane was developed by coating of porous geopolymer with nanoparticles of gamma alumina (γ-Al2O3) (Al membrane), zeolite (Z membrane), and its combination (Al-Z membrane) which were synthesized through a sol-gel method. Nanoparticles of γ-Al2O3 exhibit rod structures with 10-20 nm in diameter and 40-70 nm in length, a surface area of 326.26 m2/g, total pore volume of 0.10 cm3/g, and an average pore diameter of 2.10 nm. Zeolite nanoparticles were obtained from a composition of 6Na2O: 0.55Al2O3: SiO2: 150H2O having particle sizes in the range from 100 to 400 nm, a surface area of 97.32 m2/g, total pore volume of 0.80 cm3/g, and an average pore diameter of 11.19 nm. The performance of membranes was evaluated by measuring the salt rejection and the flux of NaCl 1% (w/v) solution that was passed through the membrane. The Z membrane demonstrated the highest salt rejection, up to 87.88%, whereas the Al-Z membrane reached 68%. The Al membrane exhibited the lowest salt rejection rate, amounted to 57.14%. The highest flux was obtained using Al membrane, which was to 3.43 × 103 L/m2h on the 54.29% rejection value; whereas the Z membrane reached 3.28 × 103 L/m2h on the 87.88% salt rejection value, and the lowest flux of 2.91 × 103 L/m2h showed by the Al-Z membrane at the 62% salt rejection value. It is promising to use the synthesized γ-Al2O3 and zeolite nanoparticles as alternative ceramic membrane materials to be applied in the desalination.[/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]Ceramic membrane materials,Gamma alumina,Pore diameters,Rod structure,Salt rejection rates,Salt rejections,Total pore volume,Zeolite nanoparticle[/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]Ceramic membranes,Desalination,Gamma alumina,Zeolite[/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]The authors gratefully acknowledge the research funding granted by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia through the PDD, PKPI program, and under the SINAS Research Grant Scheme, as well as funding provided by Bandung Institute of Technology under the Research University Grant.
