Photocatalytic and other chemical methods for textile effluent dye degradation.
| Treatment technology | Parameters | Pollutants (dyes) | Degradation efficiency | References |
| Photocatalytic process (MZC and MZG) | Contact time = 30 min | Methyl blue | 78% with MZG | [47] | Catalyst dose = 1 g/L | pH = 6 |
| Photocatalytic process (NiFe2O4/ZnwO4) | Contact time = 70 min | Rhodamine | 98% | [48] | Catalyst dose = 50 mg |
| Photocatalytic process (UV/H2O2/ZnO) | Zno (dose = 0.6 g/L) | Disperse red | 97% | [49] | pH = 9, irradiation time = 60 min and H2O2 = 0.9 ml/L |
| Photo-fenton process (activated carbon/coFe2O4 (Ac/CFO)) | Nanocomposite = 0.3 g/L | Reactive Red 198 | 100% | [50] | Contact time = 25 min | PS = 5 mM, irradiation = 30 W and current = 0.32 A |
| Photo-fenton process (calcined laterite soil) | pH = 3, H2O2 = 1 mol/L, catalyst dose = 2 g/L and contact time = 120 min | Acid red 17 | 94.71% | [51] |
| Ozonation | The ratio of H2O2 to O3 = 1 : 10500 | Direct red 80 | The highest COD removal rate was 43% | [52] |
