Abstract
The issue of clean water scarcity drives the development of membranes that are both efficient and resistant to extreme conditions. Cocoa pod husk waste, which is abundant and contains lignocellulose, antioxidants, and carbon, has potential as a sustainable coating material. This study aims to fabricate and characterize a carbon membrane derived from cocoa pod husk as a coating for alumina substrates, as well as to examine the influence of cocoa husk mass and PEG (Polyethylene Glycol) concentration on membrane permeability. The process was carried out using the brush coating method followed by carbonization at 650 °C for 2 hours under a nitrogen atmosphere. Characterization included permeability testing, Scanning Electron Microscope–Energy Dispersive X-ray (SEM-EDX), and X-Ray Diffraction (XRD). The variables used included PEG concentrations ranging from 0–8% and cocoa husk mass from 4 20%. The best composition—16% cocoa husk and 6% PEG—yielded a permeability of 94.39 L/m²·h·atm, higher than that of pure alumina membranes such as γ-Al₂O₃ (~5.6 L/m²·h) and double-layer α-Al₂O₃ (~70 L/m²·h). SEM-EDX showed active carbon distribution and microporous structures that enhanced flux and adsorption. XRD identified TiO₂ (improving hydrophilicity), carbon (porosity and adsorptivity), and Fe₂N (enhancing chemical stability and conductivity). This membrane shows potential for desalination, as demonstrated by reports of carbon–Al₂O₃ membranes with flux up to 25 L/m²·h and salt rejection above 90%. This technology offers a promising solution for low-cost clean water filtration. The limitation of this study lies in controlling the coating thickness and achieving uniformity.
