Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...
Background and Objective: N-methylpyrrolidine is a highly potent solvent with toxic and adverse ecological properties that has historically been widely used in the chemical and petrochemical industries. Due to the health and safety، toxicity and environmental effects of effluents containing NMP، these effluents should be pre-treated before biological treatment methods. The aim of this study was...
To address potential mechanisms for oxidative modification of lipids in vivo, we investigated the possibility that phospholipids react directly with glucose to form advanced glycosylation end products (AGEs) that then initiate lipid oxidation. Phospholipid-linked AGEs formed readily in vitro, mimicking the absorbance, fluorescence, and immunochemical properties of AGEs that result from advanced...
Background & Aims of the Study: The presence of antibiotics in the environment, especially in aquatic environments is a major concern for health and the environment. The advanced oxidation process due to the ease of use, economical advantages and high performance have attracted a lot of attention. The purpose of this study was Evaluating of the photocatalytic role of zinc oxide on s...
بررسی کارایی پر سولفات سدیم فعال شده با پرتو فرا بنفش در حذف آنتی بیوتیک آفلوکساسین از محیط های آبی
Background and purpose: Pharmaceutical products, particularly antibiotics are emerging contaminants that cause major environmental challenges due to cumulative effects, different adverse effects, and leading to drug resistance. The aim of this experimental study was to evaluate the efficiency of advanced oxidation process by persulfate activated by UV in removal of ofloxacin from aqueous soluti...
Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...
Background : The presence of antibiotics in water sources indicates inadequacy of conventional treatment processes for antibiotics removal. The objective of the present study is to investigate the effectiveness of the advanced oxidation process, UV/H2O2, in the removal of ceftriaxone from an aqueous solution on a laboratory scale. Materials and Methods: This experimental study was conducted on ...
Chronic obstructive pulmonary disease (COPD) is associated with cerebrovascular abnormalities and an overproduction of reactive oxygen species. We hypothesised that COPD patients have oxidant-related cerebrovascular dysfunction. Our main objective was to evaluate cerebrovascular reactivity and its relationship with oxidative stress in females with COPD. We studied eight females with moderate CO...
Many industrial activities utilize organic compounds as a key chemical in organic synthesis of special chemicals such as, synthetic resins, paper products, medicinal products, drugs, dying and others. Different chemical processes, most of them based in oxidation-reduction reactions, are being applied. Processes such as chlorination, ozonation, UV irradiation, electrochemical treatments and proc...
