We demonstrate and analyze a novel desalination method which works by electrophoretically replacing sodium and chloride in feed salt water with a pair of ions, calcium and carbonate, that react and precipitate out. The resulting calcium carbonate precipitate is benign to health, and can be filtered or settled out, yielding low ionic strength product water. The ion exchange and precipitation emp...

This study was designed to investigate the pathogenesis of chlorine gas (Cl2) induced acute lung injury and oedema. Isolated blood-perfused rabbit lungs were ventilated either with air (n=7) or air plus 500 parts per million (ppm) of Cl2 (n=7) for 10 min. Capillary pressure, measured by analysing the pressure/time transients of pulmonary arterial, venous and double (both arterial and venous) oc...

Exposure to chlorine (Cl2) gas can occur during accidents and intentional release scenarios. However, biomarkers that specifically indicate Cl2 exposure and Cl2-derived products that mediate postexposure toxicity remain unclear. We hypothesized that chlorinated lipids (Cl-lipids) formed by direct reactions between Cl2 gas and plasmalogens serve as both biomarkers and mediators of post-Cl2 gas e...

Upper-respiratory-tract symptoms (nasal irritation, congestion and rhinorrhea) are prevalent complaints in so-called "problem buildings." In epidemiologic studies, symptom reporting is associated with selected subject characteristics, including younger age, female gender, and the presence of allergic rhinitis. The physiologic correlates of these differential reporting patterns, however, are lar...

Ferrocene solubilized with poly(vinylpyrrolidone) in aqueous KCl solution exhibited a well-defined voltammetric peak at 1.33 V vs. Ag|AgCl at a platinum electrode. The wave was attributed to the oxidation of chloride to chlorine, demonstrated by smell of chlorine, by a view of formation of gas bubbles, by coloration through the reaction with diethyl-p-phenylene diamine, and by the increase in t...

INTRODUCTION An incident involving the release of chlorine gas from the pump room at a local swimming pool resulted in 54 patients seeking treatment in the emergency departments (EDs) of two local, tertiary-level hospitals in Singapore. The hospital hazardous materials (HAZMAT) disaster plan was activated. This report describes how one of the EDs organized in response to the disaster. EVENT O...

Sir Humphry Davy witnessed the first chlorine hydrate crystallizing in 1811. Couple of century later his discovery, natural gas hydrates has begun to play an important role in energy business. From being a mere chemical curiosity, they have proven to be a nuisance for the natural gas industry. The problem of hydrate induced blockage in “wet gas” flow systems has been widely reported and became ...

The currently used microbial decontamination method for spacecraft and components uses dry-heat microbial reduction at temperatures of >110°C for extended periods to prevent the contamination of extraplanetary destinations. This process is effective and reproducible, but it is also long and costly and precludes the use of heat-labile materials. The need for an alternative to dry-heat microbial ...

as a disinfectant in surgical cases, an apology is perhaps necessary : for is not the action of chlorine as a deodorizer, disinfectant, and antiseptic, well known ? But in the present day, with carbolic, boracic, and salicylic acids, thymol, &c. &c., at our disposal, we are apt to neglect old tried friends for the popular favourites. In sloughing and foul-smelling wounds an aqueous solution of ...
