This article brings information on how to protect worker health during the decommissioning of mercury-based electrolysis facilities. It relies on the Euro Chlor document "Health 2, Code of practice, Control of worker exposure to mercury in the chlor-alkali industry" that provides protection guidelines for both normal production and decommissioning activities, and on hands-on experience gained d...

The purpose of this study was to evaluate the effect of an alcohol-based caries detector (Kurakay) on the surface tension of a conventional sodium hypochlorite (NaOCl) preparation, and a product containing a surface-active agent (Chlor-XTRA). The surface tensions of the following solutions were tested: NaOCl, a mixture of NaOCl and Kurakay 9:1 w/w, Chlor-XTRA, a mixture of Chlor-XTRA and Kuraka...

introduction: the purpose of this in vitro study was to assess the antifungal activity of final canal rinse with either three concentrations of sodium hypochlorite (naocl) (0.5, 2.6 and 6%), two concentrations of chlorhexidine (chx) (2% and 0.2%), mtad, tetraclean, hypoclean and chlor-xtra on candida albicans (c. albicans ) in a human tooth model. methods and materials: two hundred and thirty f...

and Chlor-Xtra at 20 °C and 45 °C in bovine root dentin. One-hundred-and-seventy dentin tubes prepared from bovine maxillary incisors were infected for 21 days with Enterococcus faecalis. The specimens were divided into the following groups: 1. 5.25% NaOCl 20 °C; 2. Hypoclean 20 °C; 3. Chlor-Xtra 20 °C; 4. 5.25% % NaOCl 45 °C; 5. Hypoclean 45 °C; 6. Chlor-Xtra 45 °C; 7. positive control; 8. neg...

For many years the Savannah River has suffered fish consumption warnings. While several potential sources of mercury may contribute to this contamination, the chlor-alkali facility in Augusta, which produces chlorine by electrolysis using mercury-cell technology, is a major potential contributor. To examine this possibility samples of sediment were collected from the river above and below the f...

Nine preparations of six antiseptic substances were applied to the perineum of pregnant women at term in order to assess their efficacy in sterilizing the skin. The efficacy, in descending order of effectiveness, after three minutes' exposure, was p-chlor-m-xylenol in alcohol (surgical Dettol); chlorhexidine gluconate in detergent (Hibiscrub), followed by the aqueous preparations p-chlor-m-xyle...

In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function ...

Antibiotic residues have been found in environmental samples, such as water, soil, and even food, usually come from wastewater, presenting human health risks. This study aimed to improve the elimination of antibiotics tetracycline (Tet) chloramphenicol (Chlor) by modifying three factors: contact time (3–7 days), plant biomass (10–14 g), antibiotic concentration (5–15 mg/L Tet 10–20 Chlor). An a...
