The application relates to the technical field of fertilizers, and discloses a chitosan-grafted polyacrylic acid slow-release fertilizer and a preparation method thereof. The chitosan-grafted polyacrylic acid slow-release fertilizer is obtained by spray drying of a nutrient solution, a carrier dispersion liquid and a calcium chloride aqueous solution; the nutrient solution is obtained by mixing urea, potassium dihydrogen phosphate, zinc sulfate heptahydrate, iron sodium ethylenediaminetetraacetate, amino acid and deionized water; the carrier dispersion liquid is obtained by mixing a porous carrier, deionized water and polyoxyethylene sorbitan monooleate; the porous carrier is prepared from sulfonated chitosan powder, deionized water, an acrylic acid neutralizing solution, ammonium persulfate and N,N'-methylenebisacrylamide; and the sulfonated chitosan powder is prepared from formamide, chlorosulfonic acid and chitosan powder. The application can reduce the release rate of nutrients and improve the utilization rate of nutrients.

The application relates to the technical field of textiles, and discloses a fabric with moisture absorption, quick drying and antibacterial functions and a preparation method thereof. The fabric is obtained by impregnating a pure cotton fabric with a finishing working solution. The finishing working solution is obtained by mixing a finishing agent, a citric acid crosslinking agent, sodium hypophosphite, a fatty alcohol polyoxyethylene ether and deionized water. The finishing agent is prepared from hyperbranched polyamide, deionized water, 2,3-epoxypropyl trimethyl ammonium chloride, a cellulose nanowhisker aqueous solution, sorbitan monooleate polyoxyethylene ether and a sodium hydroxide aqueous solution. The hyperbranched polyamide is prepared from anhydrous methanol, ethylenediamine and methyl acrylate. The application has good antibacterial property and quick drying property.

The present application relates to the technical field of contaminated soil remediation, and discloses a composite material for halogenated hydrocarbon-heavy metal contaminated site remediation, a preparation method and application thereof.The method comprises emulsifying plant oil, polyoxyethylene sorbitan monooleate, sorbitan monooleate, sludge supernatant, nano zero-valent iron loaded on biochar and water in a mass ratio of 1:0.1-0.3:0.1-0.3:1-2:0.7-2:15-30 to obtain the composite material.The composite material prepared by the method can prevent the agglomeration of nano zero-valent iron particles loaded on biochar, and the composite material can simultaneously use adsorption, biology, chemistry and electrochemistry for halogenated hydrocarbon-heavy metal contaminated site remediation, thereby achieving the effect of efficiently removing heavy metals and halogenated hydrocarbons.
