More Information
Summary:The present investigation was carried out to Microwave (MW) and photocatalytic decomposition of synthetic lignin wastewater by using TiO2 nanoparticles and TiO2 coated activated carbon (AC). The materials were prepared and characterized by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infra-red spectroscopy and BET surface area analyzer. Synthetic lignin wastewater was used as model pollutant and two types of treatment systems were employed such as photocatalytic and MW with photocatalytic reactors. Among the systems, the MW with photocatalytic reactor treatment was found to be more efficient than photocatalytic reactor.
