This study focuses on the synthesis of a g-C3N4/Fe3O4 nanocomposite and optimization of PCP in degrading 2,4-D in water. The g-C3N4 and the g-C3N4/Fe3O4 were synthesized using a two-step direct calcination approach and co-precipitation respectively. The quality assessment of the synthesized nanocomposite was conducted through the utilization of XRD, DRS, FTIR, FE-SEM, EDS, elemental mapping, TEM and VSM analytical techniques. The quadratic model has a high F-value (152.27) and low P-value (0.0001), indicating its suitability for explaining the amplification relationship between response values. The optimum parameters for PCP to decompose 2,4-D were determined to be pH~6.5, catalyst dose~16.5 mg/L, reaction time~55.5 min, and initial 2,4-D concentration~52 mg/L (96.11% degradation efficacy). The data showed strong correlation with first-order kinetics (R2>0.95). The efficiency of the PCP is boosted by the existence of a catalyst and photolysis, which creates multiple pathways for 2,4-D breakdown. The PCP exhibited a capacity to diminish COD and TOC by 75% and 63%, respectively. The reaction time decreases with higher light intensity and 2,4-D removal is complete in 45 minutes at 60 mW/cm2. Methanol greatly affects the PCP's scavenging ability. In contrast, the impact of sodium azide was observed to be the least significant and the OH● is deemed as the principal ROS in the PCP. The results show that PO43- reduces efficiency to 72%. The PCP's ability to remove 2,4-D, COD, and TOC remained consistent even after the sixth cycle. The EE/O, 17.3 KW/h.m3.order was calculated. The intermediate products were 2,4-dichlorophenol, 2,6-dichlorophenol, 4,6-dichlororesorcinol, 2-chlorohydroquinone, and 2-chloro-1,4-benzoquinone.

“…The preparation of samples with a primary 1-naphthol solution concentration of 5 mg/L was done at pH values of 3, 5, 7, and 9. The samples were obtained and investigated at times of 0, 5,10,15,20,25,30,35,40,45, and 50 min on the catalyst's surface. To eliminate the effect of adsorption on removing 1-naphthol, all solutions were rotated for 45 minutes without the presence of light in the chamber.…”

Background:The 1-Naphthol, one of the derivatives of naphthalene, is the most significant industrial chemical that is widely used in the production of dyes, pharmaceuticals, and biochemical processes. Methods: In the present study, N, S-doped TiO2 thin film immobilized on silica sulfuric acid (SSA) glass microspheres (MS) was investigated as a novel high efficient photocatalyst. The N, S-doped TiO2 immobilized on SSA was fabricated using a simple modified sol–gel process. Its photocatalytic activities were then assessed using 1-naphthol solution in the presence of visible light. The physico-chemical properties of photocatalyst were characterized using energy-dispersive X-ray (EDX), scanning electron microscope (SEM) images and X-ray diffraction (XRD) pattern. Results: According to the obtained results, the optimal pH, time, concentration, and removal efficiency of 1-naphthol for N, S-doped TiO2 /SSA was 5, 50 minutes, 25mg/l and 92.12%. Conclusion:The present study confirms the usability of the immobilized N, S-doped TiO2 on SSA glass MS as a novel, effective, and efficient technique for treatment of wastewater containing 1-naphthol under visible light.
