TL;DR: In this paper, a Raman microscope equipped with an environmental chamber and a single particle optical levitator was used to determine the ability of sodium and magnesium chlorate salts to take up water vapor at low temperatures (296-K to 237-K).

TL;DR: The influence of concentration of hydrochloric acid, amount of sodium chlorate, solid-liquid ratio and reaction time on the recovery rate of gold from waste printed circuit boards with HCl and NaClO3 solution was investigated in this paper.
Abstract: Recovery of gold from waste printed circuit boards(PCBs) with HCl and NaClO3 solution was studied.The influence of concentration of hydrochloric acid,amount of sodium chlorate,solid-liquid ratio and reaction time was investigated.Results indicated that it was unfavorable for recovering rate of gold when acidity was too high or too low.For 5g waste material,under the condition of solid-liquid ratio of 1:8,sodium chlorate 4g,hydrochloric acid 3mol/L and reaction time 1h,the recovering rate of gold could reach above 90%,with no toxicity for reagents,cheap simple equipment and easy operation.No toxicant was produced during the reaction.

TL;DR: In this article, a method for the preparation of chlorine dioxide without production of solids was proposed, which is based on filtering a concentrated sodium chlorate solution sent from an electrolytic bath, then injecting into a generator to form a reaction mother solution, circulating in the generator and a circulating pipeline under the action of a circulating pump.
Abstract: The invention discloses a preparation method of chlorine dioxide without production of solids. The method comprises the following steps: filtering a concentrated sodium chlorate solution sent from an electrolytic bath, then injecting into a generator to form a reaction mother solution, circulating in the generator and a circulating pipeline under the action of a circulating pump, maintaining the reaction mother solution at a certain density and temperature, then adding hydrochloric acid sent from a hydrochloric acid system, reacting to generate chlorine gas, chlorine dioxide gas and sodium chloride, cooling the chlorine dioxide gas, then absorbing the chlorine dioxide gas by low-temperature chilled water to obtain a chlorine dioxide water solution, sending the chlorine gas produced by reaction into a hydrochloric acid furnace to be burned with hydrogen gas produced in the electrolytic bath to prepare hydrochloric acid, and returning a dilute sodium chlorate solution after reaction into the electrolytic bath by a pump for re-preparing the concentrated sodium chlorate solution for recycling. According to the method disclosed by the invention, the production of the solids can be prevented in the whole reaction process and scaling of equipment can be avoided, so that sodium chloride and sodium dichromate can be completely recycled and do not need to be supplemented basically.

TL;DR: The data indicate that microbial-dependent or chemical-dependent, or both, reduction of chlorate occurs in bovine ruminal fluid and that dietary concentrate had a negligible effect on chlorate reduction.
Abstract: Sodium chlorate effectively reduces or eliminates gram-negative pathogenic bacteria in the gastrointestinal tracts of live cattle. Limitations to the in vivo efficacy of chlorate are its rapid absorption from the gastrointestinal tract and its presumed reduction to chloride within the gastrointestinal tract. We hypothesized that chlorate would be reduced via ruminal bacteria in a ruminal in vitro system and that the reduction of chlorate would be influenced by the dietary for-age:concentrate ratio; thus, 4 ruminally cannulated steers were fed 20 or 80% concentrate diets in a crossover design. Ruminal fluid was collected in 2 periods and dispensed into in vitro tubes containing sodium [36Cl]chlorate, which was sufficient for 100 or 300 mg/L final chlorate concentrations. The tubes were incubated for 0, 1, 4, 8, 16, or 24 h; autoclaved, control ruminal fluid, fortified with sodium [36Cl]chlorate, was incubated for 24 h. Chlorate remaining in each sample was measured by liquid scintillation counting after [36Cl]chloride was precipitated with silver nitrate. A preliminary study indicated that chlorite, a possible intermediate in the reduction of chlorate, had a half-life of approximately 4.5 min in freshly collected (live) ruminal fluid; chlorite was, therefore, not specifically measured in ruminal incubations. The chlorate dose did not affect in vitro DM digestion (P > or = 0.11), whereas in vitro DM digestibility was decreased (P or = 0.18) on chlorate reduction; however, when chlorate reduction was expressed on a percentage basis, chlorate reduction tended to be greater (P > or = 0.09) at 8 and 16 h in the incubations containing the low-concentrate diet. Chlorate remaining in autoclaved controls at 24 h was intermediate (P < 0.01) between chlorate remaining in live ruminal fluid samples incubated for 0 or 24 h. Attempts to isolate chlorate-respiring bacteria from 2 sources of ruminal fluid were not successful. These data indicate that microbial-dependent or chemical-dependent, or both, reduction of chlorate occurs in bovine ruminal fluid and that dietary concentrate had a negligible effect on chlorate reduction.
