Carbon Membrane Material and Water Treatment Performance
Introduction
Researchers have conducted a study to investigate the influence of carbonisation temperature on the properties of membrane material and its impact on water treatment performance. This research aligns with the Sustainable Development Goals (SDGs) by addressing the need for sustainable water treatment solutions.
Methods
The synthesis and preparation of carbon membranes involved pyrolyzing sucrose at different temperatures. Alumina tubes were coated with a sucrose solution using dip-coating to create the carbon membranes. The study focused on analyzing the effect of carbonisation temperature on the characteristics of the membrane material and its desalination performance.
Results
The study found that the carbonisation temperature significantly influenced the properties of the membrane material. Thermogravimetric analysis (TGA) data showed that solid sucrose remained stable up to 210°C. Fourier-transform infrared spectroscopy (FTIR) results indicated changes in functional groups when the carbonisation temperature exceeded 200°C. Gas sorption analysis (GSA) revealed that the resulting adsorption isotherm exhibited characteristics of a mesoporous material. However, the volume and pore size of the carbon membrane material were minimal. Scanning electron microscopy (SEM) results showed that carbon distribution was uneven but dense. The carbon membrane demonstrated excellent performance in desalination, achieving 100% salt rejection and a water flux greater than 10 kg.m−2.h−1 at a feed concentration of 1% and a temperature of 60°C. Long-term testing also confirmed the high stability of the carbon membrane, with consistent salt rejection at around 100% for up to 60 hours.
Conclusion
The study’s findings highlight the importance of carbonisation temperature in modifying the characteristics of membrane material and its subsequent impact on water treatment performance. The carbon membrane demonstrated promising results in desalination, showcasing its potential as a sustainable solution for addressing water scarcity. These findings contribute to the achievement of SDG 6: Clean Water and Sanitation.
