the petrochemical industry is the most important and most widely active industries in the country. due to the variety and complexity of industrial products, it also produces a wild range of pollutants. mercury waste disposal from chlor-alkali units is one of the fundamental problems of this industry. various studies have shown that phytoremediation system for removal of mercury from aqueous sol...

The effect on the rate of tumor induction of a group of chlor-compounds which reversibly inhibit the glycolyric process of cells has already been described (5, 6). The compounds used were soluble in water and fats, and were nonhydrolyzable under physiological conditions of pH and temperature. The chemical reactivity of their chlorine atoms was the factor which determined the potency of their bi...

Abstract As an energy-intensive industry, the chlor-alkali process has caused numerous environmental issues due to heavy electricity consumption and pollution. Chlor-alkali industry been upgraded from mercury, diaphragm electrolytic cell, ion exchange membrane (IEM) cells. However, several challenges, such as selectivity of anodic reaction, sluggish kinetics alkaline hydrogen evolution, degrada...

Chlorinated organic compounds resu l t from ch lor inat ion treatment of wastewater. The discharges, containing these compounds, in to the aquatic environment have resulted in widespread concern. Invest igat ions have been conducted on the ef fects of these chloro-organics on aquatic l i f e . Most of the studies, however, have been conducted on zooplankton or higher organisms. Only l imi ted i...

The purpose of this study was to create a monoculture biofilm of a clinical isolate of Enterococcus faecalis and to determine susceptibility against four antimicrobial irrigants. Biofilms were subjected to 1-, 3-, and 5-minute exposures to one of the following irrigants: 6% sodium hypochlorite (NaOCl), 2% chlorhexidine gluconate (CHX) or one of two new products, <6% NaOCl with surface modifiers...

Because of their non-inflammability and their strong solvent properties the chlor compounds of the petroleum series have a wide and increasing use as degreasers of metal, cleansers of textiles, dry cleansers, solvents for rubber, tar, and gums, thinners for cellulose lacquers, and in treatment of garbage, tankage, and bones. Other uses are the production of high-grade lubricating oils from infe...
