Zinc Electrodeposition from Acetate Solutions
he electrodeposition of zinc on iron and steel for protection T against corrosion was first proposed in 1840. The combination of aesthetic appeal and protection thus provided has established bright zinc plating as an important process in modern industry. In today's technology, zinc is preferably deposited from acid-type electrolytes, especially chloride, as an alternative to those based on cyan...
متن کاملInactivation of poliovirus and other enteroviruses by solutions of sodium fluoride at low pH.
Solutions of sodium fluoride at pH 3 to 4 inactivated enteroviruses, whereas other sodium salts had little or no effect on virus infectivity. Solutions of potassium fluoride also inactivated viruses under similar conditions. Light, temperature, and the presence of organic compounds such as detergents and fecal matter did not affect inactivation of virus by 0.4 M solutions of sodium fluoride at ...
متن کاملINFLUENCE OF pH ON THE OXYGEN ABSORPTION KINETICS IN ALKALINE SODIUM DITHIONITE SOLUTIONS
-Results from experimental studies on the influence of pH within the alkaline range on sodium dithionite oxidation with molecular oxygen reveal that it is possible to follow the kinetics of the process by observation of the consumption of base needed to maintain a constant pH. Under the conditions studied (partial oxygen pressure higher than 20,260 N/m z, pH > 8, 295 K ~ T ~< 318 K, and a dithi...

were aged in vitro for 24 hours at 370C. Nor was the normal rate of loss of 2,3-diphosphoglycerate, ATP, or glutathione from the red cells affected by the presence of chloramphenicol over the same period. Consequently, this bacteriostatic agent can be added to blood samples taken under nonsterile conditions, such as from the heel of an infant, in order to preserve them from the effects of micro...

hypochlorite (NaOCl) associated with a surfactant. Seventy single-rooted extracted human teeth were inoculated with Enterococcus faecalis, and incubated for 21 days (37 °C). The groups were distributed according to the irrigation solution used during root canal preparation: 5%, 2.5% and 1% NaOCl; 5%, 2.5% and 1% Hypoclean®, a solution containing a surfactant (cetrimide) associated with NaOCl. T...
