Photocatalytic and photoelectrocatalytic humic acid removal and selectivity of TiO2 coated photoanode
In this study, photocatalytic (PC) and photoelectrocatalytic (PEC) treatment methods were comparatively investigated as a possible means of removing humic acid (HA) following absorbance at 254 nm (UV254) and total organic carbon (TOC) analysis. The enhanced HA degradation rates were obtained in the...
