Catalyst | Abbreviations | Conditions | Efficiency | References |
|---|---|---|---|---|
Chitosan-capped MnO2-iridium nanoparticles supported on nanoceria | [Ch-MnO2-Ir/CeO2] | The oxidative degradation of acid orange 7 in an aqueous solution by activated persulfate at 30 °C, pH 9.0 | The catalyst shows 80% degraded 70.06 mg/L of acid orange 7 within 100 min | |
Vanadium–titanium magnetite was investigated in the decolorization of Acid Orange II by a non-homogeneous Fenton process | [V-Ti]/Fe3O4 | The experiments were carried out at 25 °C and the dosage of the catalyst was 0–2.0 g/L while the concentrations of AO7 and H2O2 were 0.2 mmol/L and 0–20 mmol/L | The mineralization rate was about 30% 4 h after the degradation started | |
Waste printed circuit board was used as a novel catalyst for the degradation of orange II with H2O2 | [w-PCB] | Orange II degradation was carried out under conditions of w-PCB 2 g/L, H2O2 5 mL/L, pH 7.9, orange II 0.1 mmol/L, and temperature 40 °C | 97.98% degradation of Orange II was carried out within 6 h with (w-PCB) | |
Heterogeneous Fenton-like Degradation of Orange II in Water Using FeZSM-5 Zeolite Catalyst | [FeZSM-5] | The degradation of orange II performance at 266.7 mM H2O2 at 50 °C for 0.05 g/dm3 of [orange II] solution at a pH 7.0 | A color removal of 99.99% and a COD elimination of 55.0% were achieved after a reaction time of 2 h | |
chitosan/MMT biocomposite in the Sono-assisted adsorption removal of AO7 | [chitosan/MMT biocomposite] | The experiments were carried out under conditions of 1 g/L [chitosan/MMT], 200 mg/L [AO7], 350 W ultrasonic power, and pH 6.95 | Removal efficient 51.8% within time: 60 min | |
Cobalt (II) complex of 5,10,15,20 tetrakis-[4-(hydroxy)phenyl] porphyrin supported on chitosan/Graphene Oxide nanocomposite | [Co(II) TPHPP]-Cs/GO | The experiments were carried out at (1.42 × 10−4 M) AO7 dye, with H2O2 (8 × 10−2 M) in the presence of [Co(II) TPHPP]-Cs/GO nanocomposite (15 × 10−3 g/mL) and pH = 9 at 40 °C | removal efficiency of AO7 94%, within 60 min, TOC shows 50%dye mineralization, high catalytic stability, and no significant change up to six runs | Present work |
