Water 2019 v.11 no.6 pp. -
ISSN:
2073-4441
Subject:
activated carbon; adsorption; air; carbon dioxide; chloramphenicol; equations; micropores; models; pH; sorption isotherms; surface area; water treatment; water vapor
Abstract:
... The aim of the study was to evaluate the possibility of applying commercial activated carbons currently used in water treatment plants and modified carbon at 400 and 800 °C in the atmosphere of air, water vapour and carbon dioxide to remove chloramphenicol. Adsorption kinetics was examined for solutions with pH of 2–10. Adsorption kinetics were determined for the initial concentration of ...

ISSN:
0045-6535
Subject:
aeration; air; chloramphenicol; dissolved oxygen; free radicals; iron; overdose; oxidants; oxygen; pH; sulfites; wastewater
Abstract:
... In this study, an Fe(Ⅱ)/S(IV) system was designed for the degradation of chloramphenicol (CAP). The pseudo-first-order rate constants for CAP degradation under typical conditions with and without air purging were investigated. The greatly enhanced rate of 0.0099 min−1 with air purging compared with 0.0006 min−1 with no air purging indicated that aeration was significant to the degradation of CAP i ...

Subject:
acetonitrile; air; albendazole; chemometrics; chloramphenicol; eggs; enrofloxacin; liquid chromatography; liquid-phase microextraction; methanol; methylene chloride; nicarbazin; pH; sodium phosphate; solidification; solvents; trimethoprim; veterinary drugs; zinc sulfate
Abstract:
... Two extraction strategies for albendazole, chloramphenicol, trimethoprim, enrofloxacin, oxitetracycline and nicarbazin in egg were optimized for its quantitation by liquid chromatography. First, two designs were built to find out the optimized condition for the air assisted-dispersive liquid-liquid microextraction based on solidification of organic drop: a fractional factorial and a central compos ...

Abstract:
... Fungal bio-aerosols are of concern due to their adverse health effects, especially in indoor environments. The aim of this study was to evaluate the relationship between the concentration and type of fungal bio-aerosols in the indoor and outdoor of Children’s Medical Center in Tehran, Iran. In the present descriptive-analytical study, the fungal bio-aerosols’ concentrations in both indoor and outd ...

Aspergillus niger; Fusarium; Paecilomyces; Penicillium; adverse effects; agar; air; airborne microorganisms; bioaerosols; chloramphenicol; fungi; glucose; hospitals; patients; temperature; ventilation systems
Abstract:
... Fungi are one of the bioaerosols in indoor air of hospitals. They have adverse effects on staff and patients. The aim of this study was to investigate the effects of three incubation temperature on the density and composition of airborne fungi in an indoor and outdoor space of hospital. Sabouraud dextrose agar was used for culture the fungi. For improvement of aseptic properties, chloramphenicol w ...
