متن کاملSUBSTANCE PROFILES Strong Inorganic Acid Mists Containing Sulfuric Acid CAS No. 7664-93-9 (Sulfuric Acid)
Strong inorganic acid mists containing sulfuric acid are known to be human carcinogens based on sufficient evidence of carcinogenicity from studies in humans that indicate a causal relationship between exposure to strong inorganic acid mists containing sulfuric acid and human cancer. Occupational exposures to strong inorganic acid mists containing sulfuric acid are specifically associated with ...
متن کاملStrong inorganic acid mists containing sulfuric acid.
Occupational exposure to strong inorganic acid mists containing sulfuric acid is specifically associated with laryngeal and lung cancer. Studies of one U.S. cohort of male workers in pickling operations in the steel industry found excesses of laryngeal cancer (approximately twofold) after adjustment for smoking and other potentially confounding variables (Steenland et al. 1988). A ten-year foll...
متن کاملKinetics of Sphalerite Leaching by Sodium Nitrate in Sulfuric Acid
In the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. The effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (S/L) ratio were analyzed. The dissolution rate increased with increase in the sulfuric acid an...
متن کاملOrdering of poly(3-hexylthiophene) in solution and on substrates induced by concentrated sulfuric acid.
The ordering of poly(3-hexylthiophene) (P3HT) molecules in dilute P3HT/chloroform solutions was accelerated by adding small amounts of concentrated H2SO4. The concentrated H2SO4 stimulates the nucleation of crystals, which controls the overall rate of P3HT crystallization. Dispersed nuclei spur P3HT solution crystallization, and adsorbed nuclei induce P3HT crystallization on substrates. By AFM,...
