摘要

This study presents the synthesis of carbon membranes for desalination, utilizing honey as a natural carbon source. The investigation examines the impact of pyrolysis temperature (250 °C to 400 °C) on the structural and functional properties of the membranes. The membranes are fabricated through a dip-coating process followed by pyrolysis, forming a carbon layer on tubular alumina substrates. Thermogravimetric analysis (TGA) indicates significant weight loss between 230 °C and 400 °C, corresponding to honey carbonization. Scanning Electron Microscope (SEM) analysis reveals thinner carbon structures at higher pyrolysis temperatures. The membranes exhibit a V-type isotherm, characteristic of mesoporous materials, and Fourier-transform infrared spectroscopy confirms the presence of C = C bonds, signifying successful amorphous carbon formation. Membranes calcined at 300 °C achieve ≈ 99% salt rejection with a flux of 4.5 kg m⁻² h⁻¹, balancing high selectivity and moderate productivity. Performance trends show increased water flux with higher feed solution temperatures and reduced flux with higher feed concentrations. Notably, the membranes maintain stable desalination efficiency for up to 60 h of continuous operation. These findings demonstrate the potential of honey-derived carbon membranes as a sustainable and effective solution for desalination, offering a novel approach to achieving efficient and selective water purification.
