Chemosphere. 2023 Sep 15:140197. doi: 10.1016/j.chemosphere.2023.140197. Online ahead of print.ABSTRACTUsing guar gum (GG) as the raw material and borax (B) as the cross-linker, zeolitic imidazolate framework-8 (ZIF-8) was in-situ loaded into the 3D network of GG hydrogel, forming a highly efficient catalytic material GG-B-ZIF-8 combined with a subsequent low-temperature calcination process. In GG-B-ZIF-8 activated peroxymonosulfate (PMS) system, binary norfloxacin (NOR) and ciprofloxacin (CIP) could be removed simultaneously, with the degradation efficiency of >99.9% within 1 h.

Chemosphere. 2023 Sep 14:140181. doi: 10.1016/j.chemosphere.2023.140181. Online ahead of print.ABSTRACTThe work attempts to construct a highly effective γ-Bi2O3/CoFe2O4/Ag visible active photocatalyst for the enhanced degradation of ciprofloxacin (CIP) and Cr(VI) reduction. γ-Bi2O3/CoFe2O4/Ag photocatalyst was prepared by simple solid phase and co-precipitation methods. The nanosphere shaped CoFe2O4 photocatalyst are embedded on top of γ-Bi2O3 nanotriangle. The addition of Ag into γ-Bi2O3/CoFe2O4 heterojunction primitively facilitates the photocatalytic activity in higher rate. The quantitative analysis of photocatalys...

Multi-antibiotics removal under UV-A light using sol-gel prepared TiO < sub > 2 < /sub > : Central composite design, effect of persulfate addition and degradation pathway study
Chemosphere. 2023 Sep 1:140025. doi: 10.1016/j.chemosphere.2023.140025. Online ahead of print.ABSTRACTThe removal of three antibiotics i.e., metronidazole (MNZ), ciprofloxacin (CIP) and tetracycline (TET), from aqueous system via TiO2 photocatalysis under UV-A light was investigated. Photocatalyst(s) were prepared using sol-gel method under different calcination temperatures (400-800 °C) and water-alcohol ratio. The spherical shaped catalyst (mean particle size ∼ 61 nm) was characterized via FTIR, XRD, BET, SEM, Raman, XPS, UV-DRS, and Fluorometry, and point of zero charge was also determined (pHPZC ∼ 6.6). Batch phot...

Production of MgFe < sub > 2 < /sub > O < sub > 4 < /sub > /activated carbons derived from a harmful grass Cynodon dactylon and their utilization for ciprofloxacin removal
Chemosphere. 2023 Aug 19:139891. doi: 10.1016/j.chemosphere.2023.139891. Online ahead of print.ABSTRACTCynodon dactylon, an invasive species, exhibits its robust adaptability, reproduction and nutrient regime against the local species. Taking advantage of this harmful grass as a raw precursor to produce valuable materials for wastewater treatment has paid much attention. Herein, we report on the fabrication of Cynodom dactylon derived MgFe2O4@AC with a main goal of effective removal of ciprofloxacin antibiotic from water. Our findings showed that MgFe2O4@ACK1 composites attained mesoporous textures, high specific surface a...

Occurrence and risk assessment of pharmaceuticals in hospital wastewater in Costa Rica
Chemosphere. 2023 Aug 5:139746. doi: 10.1016/j.chemosphere.2023.139746. Online ahead of print.ABSTRACTThis work aims to determine the occurrence, hazard and prioritization of pharmaceuticals from hospital wastewater in Costa Rica through the monitoring of 70 compounds and assessing their environmental risk through a hazard quotient approach (HQ). Moreover, the quantification of selected antibiotic resistance genes (ARGs) was conducted for the first time in this matrix in this geographical location. Thirty-four pharmaceuticals were detected, being caffeine, 1,7-dimethylxanthine, acetaminophen, ibuprofen, naproxen, ciproflox...

A novel tungsten diselenide nanoparticles for enhanced photocatalytic performance of Cr (VI) reduction and ciprofloxacin (CIP)
Chemosphere. 2023 Aug 3:139701. doi: 10.1016/j.chemosphere.2023.139701. Online ahead of print.ABSTRACTNanoparticles (NPs) fabrication is a significant approach to enhance the visible light response of photocatalysts, to realize inexpensive and more harmful compound removal, at larger scale. The poor electrons and holes separation capability and low light activity of bulk materials can be notably enhanced through developing NPs. From photocatalytic investigation, better performance was received in the tungsten diselenide (WSe2) NPs than that in bare WSe2, exhibiting the action of restrained recombination of charge carriers ...
