Embodiment 1

[0029] Preparation of polyurethane solution: Dissolve 3g of polyurethane in 15mL of N,N-dimethylamide solvent, heat in a water bath and reflux for 20min.

[0030] Preparation of poly-L-lactic acid solution: Dissolve 3g of poly-L-lactic acid in 25mL of glacial acetic acid and magnetically stir until the solution is uniform.

[0031] Take 10 g of aluminum oxyhydroxide and disperse it in 1200 mL of ethanol solution (concentration: 50%), and stir the solution evenly to obtain an aluminum oxyhydroxide solution. Under the protection of an inert gas, the potassium citrate was heated up to 1200°C at a heating rate of 2°C / min and calcined for 2 hours, then kept for 30 minutes, and cooled to room temperature to prepare carbon nanosheets. Then take 10 g of carbon nanosheets and add them to 600 mL of oxidizing acidic solution (a mixture of sulfuric acid, nitric acid, and hydrogen peroxide in a volume ratio of 0.3:0.8:0.2) to prepare porous carbon nanosheets through an oxidation reaction. ...

Abstract

The invention discloses a preparation method of a landscape water treatment purification material. The method comprises the following steps: (1) dispersing aluminum oxyhydroxide into an ethanol watersolution, uniformly stirring to obtain a AlOOH solution, heating a carbon material precursor to 1000-1200 DEG C at a heating rate of 1-3 DEG C / min under the protection of inert gas, calcining for 1-3hours, keeping the temperature for 30 minutes, cooling to room temperature to obtain carbon nanosheets, and adding the carbon nanosheets into an oxidizing acid solution for oxidation reaction to obtain porous carbon nanosheets; (2) soaking the porous carbon nanosheet into the AlOOH solution, carrying out ultrasonic treatment for 20-30 minutes, then sequentially adding a polyurethane solution and apoly L-lactic acid solution, and continuously carrying out ultrasonic treatment for 30-60 minutes to obtain a blended solution; and (3) placing the blended solution in an environment with the vacuumdegree of 0.05-0.1 MPa for 3-5 hours, casting the blended solution on a stainless steel mold, drying to obtain a film, washing the obtained film with deionized water 2-3 times, and drying in a vacuumdrying oven with the temperature of 20-30 DEG C for 18-24 hours to obtain the product. The landscape water treatment purification material disclosed by the invention is good in toughness and has a good treatment effect on landscape water.

Description

technical field [0001] The invention belongs to the technical field of landscape water treatment, and in particular relates to a landscape water treatment purification material and a preparation method thereof. Background technique [0002] Landscape water usually refers to water bodies used for visual appreciation, and is usually divided into two categories: one is natural water features, such as natural lakes, rivers, etc.; the other is artificial water features, such as fountains, artificial lakes, small urban rivers, etc. With the improvement of living standards, people's requirements for the living environment are getting higher and higher. As a part of the living environment, urban water landscape not only increases the ornamental value, but also increases the water vapor cycle and plays a role in regulating the microclimate. However, the ensuing landscape water pollution is also becoming more and more prominent. The deterioration of landscape water quality and eutroph...
