  • Publication number: 20230416145
    Abstract: The present disclosure relates to a visible light-catalyzed translucent concrete, and a preparation method and use thereof. The preparation method includes: extracting an iron oxide from a copper slag, mixing the iron oxide with TiO2 to obtain a photocatalyst, and then mixing the photocatalyst with an additive to obtain a photocatalytic slurry; preparing a concrete slurry using the copper slag after iron extraction as an aggregate; and pouring the photocatalytic slurry, the concrete slurry, and the photocatalytic slurry in sequence into a mold pre-laid with an optical fiber, to obtain the visible light-catalyzed translucent concrete. In the visible light-catalyzed translucent concrete, iron in the copper slag is used as a part of raw materials of the photocatalyst, and the copper slag after iron extraction is used as an aggregate to replace natural sand and gravel. This solves environmental pollutions caused by the copper slag and realizes resource utilization.

  • Publication number: 20230303402
    Abstract: The present disclosure provides a preparation method of nano-aluminum oxide (nano-Al2O3) with a controllable hydroxyl content, belonging to the technical field of nano-alumina. H2O2 dissolved in water dissociates a large number of hydroxyl radicals. In the present disclosure, a resulting H2O2 solution is used as a solvent for precipitation; during the precipitation, a soluble aluminum salt and a pore-enlarging agent are reacted to generate a precipitate under alkaline conditions, and the hydroxyl radicals are distributed on a surface of the precipitate. During drying, the hydroxyl radicals are converted into bound water and distributed on a surface and in pores of an aluminum hydroxide precursor; during roasting, the bound water is destroyed to form hydroxyl. The hydroxyl content of the nano-Al2O3 can be regulated by controlling a concentration of the H2O2 solution, and the nano-Al2O3 has the hydroxyl content positively correlated with the concentration of the H2O2 solution.

  • Patent number: 11261088
    Abstract: A method for production of ammonium phosphate from phosphate rock slurry. The method includes: introducing flue gas containing SO2 into a phosphate rock slurry, to yield an absorption solution; evaporating waste ammonia water containing 10-20 wt. % ammonia to yield ammonia gas; introducing the ammonia gas into the absorption solution at a temperature of 110-135° C. until a neutralization degree of the absorption solution reaches 1.5-1.6, thus yielding an ammonium phosphate solution and calcium sulfate; separating the calcium sulfate from the ammonium phosphate solution; and introducing the ammonium phosphate solution to a granulator for granulation to yield ammonium phosphate granules; drying and sieving the ammonium phosphate granules, thereby yielding ammonium phosphate.

  • Patent number: 4816402
    Abstract: Hybridoma HB 8986 produces a murine monoclonal antibody which recognizes a new determinant expressed in bronchopulmonary carcinomas and A549 cell line derived tumors. Immunoperoxidase staining with the hybridoma on formalin fixed, paraffin embedded tissues shows that it specifically stains both the cytoplasmic and cell surface. The monoclonal antibody has the ability to distinguish preferably bronchopulmonary carcinomas with glandular differentiation from other bronchopulmonary carcinomas. Additionally, the monoclonal antibody may identify adenocarcinomas through the body.
