Photo-Fenton reaction for the degradation of sulfamethoxazole using a multi-walled carbon nanotube-NiFe2O4 composite

Reusable Fe3O4/SBA15 Nanocomposite as an Efficient Photo-Fenton Catalyst for the Removal of Sulfamethoxazole and Orange II

“…The TOC removal percentages reached values above 60% and the degradations of the target compound were, except in the first cycle, above 75% after five hours of reaction ( Figure 8 ). The degradation values were in the ranges of the obtained by other authors both for photo-Fenton processes [ 44 , 47 ] and semiconductor photocatalysis [ 48 ]. The differences on the values could be originated because the use of a real wastewater matrix can interact to radical formation, diminishing the efficiency of the process.…”

“…Since the degradation of OII and SMX is non-specific and the reaction pathways are branched, the TOC values provide global information on the extent of degradation of the target compounds after treatment. Considering the molecular composition of OII and SMX, the expected reaction products after complete mineralization are CO 2 , H 2 O, NH 4 + , NO 3 − , SO 4 − and mineral acids [ 44 ].…”

Practice on treating pharmaceutical compounds (antibiotics) present in wastewater using biosorption techniques with different biowaste compounds. A review

“…The PPCP antibiotics used in curing these Endocrine disrupting chemicals (EDCs) are distributing to the environmental aquatic system and slowly degrading the water bodies. There are many studies involved in degrading this trace from wastewater like fabrication of manganese‐incorporated iron oxide‐graphene nanocomposite (rGO‐FMBO) is proved as an efficient activation of CaO 2 and generation of reactive radicals in the degradation of SFM, the results of this study has indicated that the CaO 2 can be activated by rGO‐APTMS‐FMBO for the effectual degradation of SFM from wastewater, 94 The combination of 20 mg/L FeCo 2 S 4 ‐CN and 0.15 mM PMS has exhibited a high catalytic activity toward SFM degradation upto 91.9%, 95 Nano‐Ag particles improved light absorption acted as electron sink for capturing photogenerated electrons and promoted the separation of photo‐induced charge showing 99% SFM degradation, 96 in other studies, NiFe 2 O 4 was considerably improved by the assimilation of 25 wt% CNT‐Carbon nanotubes, and complete degradation of SFM (5 mg/L) is achieved within 2 hr using NiFe‐CNT composite (0.025 g/L) in the presence of H 2 O 2 under UV‐Alight, 97 The influence of different range of operational parameters, which includes the initial pH, dosages and Fe2+ zeolite and water matrix on the removal of SMX were investigated in novel heterogeneous advanced oxidation process has removed SFM from contaminated water 98 …”

Graphene-Based Photo-Fenton Catalysts for Pollutant Control

“…With a narrow band gap of 2.10 eV, NiFe 2 O 4 has the potential to be a photocatalyst because of its stable structure, high electrical resistance, and photochemical stability. The ferromagnetism stemming from its magnetic moment of the antiparallel spin between the Ni 2+ ion and the Fe 3+ ion reduces the cost of catalyst recovery [40]. Liu et al [41] loaded NiFe 2 O 4 on GO sheets through a facile hydrothermal method and performed the degradation of MB with the addition of a GO-NiFe 2 O 4 composite, visible light, and oxalic acid.…”
