Photocatalytic Efficiency of TiO2-Biomass Loaded Mixture for Wastewater Treatment
The objective of this study was to assess the efficiency of a novel TiO2/modified sago bark (TiO2/MSB) mixture for the degradation of sago wastewater effluent by employing response surface methodology (RSM) using chemical oxygen demand (COD) removal as the target parameter. The highest COD removal o...
