44 results about "Hydronium" patented technology

In chemistry, hydronium is the common name for the aqueous cation H3O+, the type of oxonium ion produced by protonation of water. It is the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H+) to the surrounding water molecules (H2O).

Photocatalysis air purifier

The invention discloses an efficient photochemical catalysis air purifier, which consists of a machine box, a filtering device, a fan and a photochemical reacting room. The photochemical reacting room includes a three-dimensional honey comb ceramic halftone which loads a photocatalyst of nano-composite TiO2 and an ultraviolet radiation light which irradiates towards the honey comb ceramic halftone. The photocatalyst is TiO2 adulterated with little iron, lanthanum or cerium hydronium, and the quantity of the added hydronium is 0. 005 percent to 0.5 percent of the total weight. The three-dimensional honeycomb ceramic net of a photocatalyst carrier is a honeycomb ceramic, which is provided with 100 to 600 holes per square inch. The polluted air follows a wind inlet fan to go through the filtering device which consists of a primary filtering net and an active carbon filtering net, and granular articles are removed and volatile organic matters with peculiar smell are absorbed; the gas after primary purifying goes into the photochemical reacting room which is provided with the ultraviolet radiation light, the photocatalyst of nano-composite TiO2 and the three-dimensional honey comb ceramic net, and under an effect of a strong oxidizer which is produced by the reaction of the ultraviolet radiation and the photocatalyst, various organic pollutants in the air can be effectively decomposed.

The invention relates to a nanometer zirconia sol and a preparation method thereof. The proposal comprises the following steps that: firstly, an industrial zirconium oxychloride solution with a concentration of between 0.1 to 3 mol/L and ammonia water with a concentration of between 1 and 3.5 mol/L are slowly dripped into an ammonium chloride buffer solution with a concentration of between 0.1 and 1.5 mol/L at a temperature of between 25 and 35DEG C under stirring conditions, the pH value of the mixed solution is controlled to be between 8 and 10, and the mixed solution is continuously stirred for 0.5 to 1 hour to obtain a precursor, namely a zirconium hydroxide hydrate precipitate; then the zirconium hydroxide hydrate precipitate is scrubbed and carried out suction filtration for 2 to 4 times to obtain a filter cake; then the filter cake is dispersed into water according to the mol ratio that the zirconium hydroxide hydrate to nitric acid solution to the water is 1: 0.8-1.5: 40-200, and the nitric acid solution is dripped during the stirring to obtain an emulsion; and finally, a surfactant which accounts for 0.1 to 1.5 percent of the volume of the emulsion and a complexing agent which accounts for 0.5 to 3 percent of the volume of the emulsion are added into the emulsion respectively, the mixture is continuously stirred for 0.25 to 0.5 hour, and the mixture is heated for 6 to 20 hours in water bath at a temperature of between 85 and 90 DEG C to obtain the nanometer zirconia sol.

Method for removing magnesium ion and calcium ion in middle-degree brine in salt-field

InactiveCN101139101APotassium chloride content increasedReduce evaporation resistanceAlkali metal chloridesPotassiumSea salt
The present invention relates to a method to wipe off magnesium hydronium and calcium hydronium by the moderate brine of salt field so as to improve sodium chloride output and quality in a sea salt production zone. When the brine of salt field reaches to 10 to 18 degrees Be', the magnesium hydronium is wiped off by electric lime waste residues. The amount ratio of the electric lime to the brine is 1 : 2.5 to 1 : 4. When the concentration of the electric lime reaches to 30 to 60 g / l, the pH value of the brine in the magnesium wiping off process keeps on 11 to 12.5. When the brine approaches to saturation, mirabilite and a few sodium carbonates are added in the brine to wipe off rest calcium hydronium. The invention leads the composition of beach field brine to generate qualitative change and reduces vaporizing impedance. The brine salt producing amount of unit volume and the potassium chloride content in the salt producing mother liquor have been improved greatly. The invention has not only reduced crystallization area, improved salt quality, but also simplified salinization technics. Under the same output and irrigating pool depth, the invention can save 21 percent beach field area. The production can be increased by 10 percent under the same production area.
