Sonolysis of trichloroethylene and carbon tetrachloride in aqueous solution

Sonolysis of Carbon Dioxide, Nitrous Oxide and Methane in Aqueous Solution

Ultrasonic Waves, Carbon Dioxide, Nitrous Oxide, Methane, Free Radicals Water was irradiated with ultrasonic waves under an argon atmosphere which contained small amounts of carbon dioxide, nitrous oxide or methane. The yield of the products was measured as a function of the composition of the gas atmosphere. Maximum yields were observed at a few per cent of the added polyatomic gas. No chemica...

Effects of trichloroethylene, 1,1,1-trichloroethane and carbon tetrachloride on plasma lipoproteins of rats.

Effects of single intraperitoneal administration of trichloroethylene, 1,1,1-trichloroethane, and carbon tetrachloride (positive control) on the plasma contents of lipoproteins were investigated in rats. Plasma was fractionated to VLDL, LDL, and HDL by sequential ultracentrifugation. On the administration of carbon tetrachloride at 30 to 1000 mg/kg, VLDL and HDL were reduced dose-dependently, b...

Effect of hydrogen peroxide on the decomposition of monochlorophenols by sonolysis in aqueous solution.

The decomposition rates of several monochlorophenol by sonolysis were enhanced by the presence of hydrogen peroxide. An optimum concentration of hydrogen peroxide was observed for achieving maximum sonolysis rate of monochlorophenol. The decomposition rates of 3-chlorophenol by sonolysis were higher than those for 2- and 4-chlorophenol for most experiments conducted, suggesting that the ring st...

Carbon Tetrachloride in Helminthiasis

In the Journal of the American Mcdical Association of November 19th, 1921, there appeared a note by Maurice C. Hall on the use of Carbon tetrachloride for the removal of hookworms in animals. Dr. Hall is the senior zoologist, United States Bureau of Animal Industry, and he found this drug to be a powerful anthelmintic in dogs* and suggested its trial in human uncinariasis. Carbon tetrachloride ...
