Abstract This work investigated the usability of activated carbon walnut shell (ACWS) and magnetic (MACWS) for Bisphenol-A (BPA) elimination from aqueous solution. Fourier-transform infrared (FT-IR) X-ray diffraction (XRD) were used to study chemistry adsorbents. Batch sorption studies at different temperatures, contact time, adsorbent dosage, pH varied concentrations performed, while pseudo-fi...
زمینه و هدف: (BPA) Bisphenol A، یک زنواستروژن محیطی است که به عنوان مونومر برخی پلاستیک ها (پلی کربنات ها و اپوکسی رزین) به طور وسیعی در تولید انواع مواد وسایل از جمله مواد پر کننده دندان، ظروف یکبار مصرف و پوشش های داخلی قوطی های کنسرو استفاده می شود. این ماده به دلیل داشتن اثرات استروژنی روی سیستم تولید مثل، جز مخرب های اندوکرینی طبقه بندی می گردد. تحقیق حاضر به منظور تعیین اثر Bisphenol A رو...
volume 117 | number 3 | March 2009 • Environmental Health Perspectives Recently, Time magazine published an article titled “The Year in Medicine: From A to Z” (Park et al. 2008). The letter “B” was represented by the controversy over bisphenol A, a ubiquitous chemical used in polycarbonate and polyvinyl chloride plastics and epoxy resins and found in the urine of > 90% of Americans. The debate ...
Nowadays water scarcity represents a threat for human and living beings. Therefore, to satisfy the demands of people clean safe water, new technologies wastewater treatment have been developed. Thus, photocatalysis has emerged as green chemical approach such treatment. In this context, polyoxometalate (POM)/polymer composites with relevant photocatalytic properties developed via an easy cheap p...
In the present work, an attempt has been made to develop high-performance polymeric hybrid binary blends of epoxy/benzoxazine and benzoxazine/cyanate ester with varying weight percentages (25/75, 50/50 75/25 wt%) resins, namely, bisphenol-F epoxy resin (DGEBF), benzoxazines [bisphenol–F/aniline (BF-a) imidazole core-based bisphenol/aniline (IBP-a)] cyanate [bisphenol-F bifunctional (BF-CE)]. Th...
background: bisphenol a (bpa), an environmental pollutant, can generate free radicals which damages the reproductive system. vitamin c is an antioxidant which may prevent the adverse effects of free radicals.objective: the aim was to investigate the effect of vitamin c on the ovary tissue in rats treated with bpa.materials and methods: in this experimental study, 24 female wistar rats (200±20 g...
