Introduction and purpose: The release of chlorinated organic compounds (COCs) is accounted as a danger for public health and environment due to their harmful effects such as carcinogenicity, toxicity, and flammability. Trichlorethylene (TCE) is one of the most famous COCs, which is commonly used as a solvent for dry-cleaning and industrial degreasing and contaminates so...
The release of azo dye contaminants from textile industries into the environment is an issue major concern. Nanoscale zerovalent iron (nZVI) has been extensively studied in degradation pollutants such as methyl orange (MO). In this study, was coupled with copper and silver to make trimetallic Fe/Cu/Ag nanoparticles, order enhance MO increase reactivity catalyst by delaying rate oxidation iron. ...
Six new 9-hydroxybriarane diterpenoids, briarenolides ZI-ZVI (1-6), were isolated from a gorgonian coral Briareum sp. The structures of briaranes 1-6 were elucidated by spectroscopic methods and by comparison of their spectroscopic data with those of related analogues. Briarenolides ZII (2) and ZVI (6) were found to significantly inhibit the expression of the pro-inflammatory inducible nitric o...
This study proposed a sequential redox process to partially degrade tetrabromobisphenol A (TBBPA) within reactor great extent. After 72 hours in an anoxic environment, 20 ppm of TBBPA could be effectively degraded by sulfurized zerovalent iron nanoparticles (S-nZVI) at concentrations 2 g L-1 and 4 L-1. Biphenol (BPA) together with tri-, di-, monobromobisphenol was detected high-performance liqu...
