Synergistic Removal of Humic Acid in Water by Coupling Adsorption and Photocatalytic Degradation Using TiO₂/Coconut Shell Powder Composite

Figure 5

Comparison of the apparent first-order degradation rate constant () values between TCNSP composite and NZLC (loading amount of TCNSP & NZLC = 20 g/L and light source = 8.4 mW/cm² of UVC) ( values of NZLC extracted from [6]).
