Embodiment 1

[0041] a), select fresh water hyacinth to remove impurities, dry and pulverize to make water hyacinth solid particles;

[0042] b), take 0.5mol / L hydrochloric acid aqueous solution as solvent, take 1mL30% hydrogen peroxide and 25gFeCl 3 ·6H 2 O dissolves, stirs, and makes iron trichloride-hydrogen peroxide double catalyst;

[0043] c), take 1.0g of the water hyacinth solid particles of step a) and join in the ethanol solution with a mass concentration of 2%, after mixing evenly, add the double catalyst of step b), after stirring evenly, in an oil bath at a temperature of 110°C Heating in medium temperature and continuously stirring for 6 hours, the liquid was taken and the degradation was completed.

[0044]In order to evaluate the catalytic degradation efficiency of the aquatic plants, the resulting degradation solution was filtered to separate the solid residue, which was washed twice with water and dried at 50 °C to constant weight. After washing and drying, the weight o...

Embodiment 2

[0046] a), select fresh water hyacinth to remove impurities, dry and pulverize to make water hyacinth solid particles;

[0047] b), using 1mol / L hydrochloric acid aqueous solution as solvent, take 1mL hydrogen peroxide, CuCl with a molar ratio of 1:5 2 2H 2 O and FeCl 3 ·6H 2 O dissolves, stirs, and makes cupric chloride / iron trichloride-hydrogen peroxide double catalyst;

[0048] c), take 2.0g of the water hyacinth solid particles of step a) and join in the glycerol solution whose mass concentration is 5%, after mixing evenly, add the double catalyst of step b), after stirring evenly, in a temperature of 100°C Heat in an oil bath, and continue to stir for 6 hours, and the liquid is taken to complete the degradation. The obtained solid residue was separated by filtration, washed, dried, etc., and the weight of the solid residue was weighed, and the degradation rate of the water hyacinth of this embodiment was calculated by the formula. The results are shown in Table 1.

Embodiment 3

[0051] a), select the fresh Herba Aculotus to remove impurities, dry and pulverize it to make solid granules of Herba Aerulea;

[0052] b), with 1.5mol / L hydrochloric acid aqueous solution as solvent, take 0.2mL hydrogen peroxide and 25gNiCl 2 ·6H 2 O dissolves, stirs, and makes nickel dichloride-hydrogen peroxide double catalyst;

[0053] c), take 0.5g of step a) and add the water plank lotus solid particles into a 5% ethanol solution, after mixing evenly, add the double catalyst of step b), after stirring evenly, in an oil bath with a temperature of 80°C Heat in the pot, and keep stirring for 3 hours, take its liquid and the degradation is completed. The obtained solid residue was separated by filtration, washed, dried, etc., and the weight of the solid residue was weighed, and the degradation rate of A. japonicus in this embodiment was calculated by the formula. The results are shown in Table 1.

Abstract

The invention discloses a method for degrading aquatic plants. The method comprises the following steps: in an acid environment, mixing a metal salt and a hydrogen peroxide solution to obtain a metal salt-hydrogen peroxide dual catalyst; and in the presence of a cosolvent, carrying out catalytic reaction on the aquatic plants under the action of the metal salt-hydrogen peroxide dual catalyst to obtain the degraded aquatic plants. The method has the advantages of simple and quick operation steps, low consumption and high efficiency in the preparation process, and low cost, can achieve the degradation effect under the reaction conditions of low temperature and atmospheric pressure, and provides a new way for recycling aquatic plants. The experimental result indicates that the degradation rate of the method for aquatic plants is 55-67%.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, in particular to a method for degrading aquatic plants. Background technique [0002] Aquatic plants refer to plants that can live in water for a long time. Common aquatic plants include: water hyacinth, hollow lotus, water floating lotus, Spartina alterniflora, and Spartina alterniflora. Among them, most aquatic plants such as water hyacinth, hollow lotus, and water floating lotus are invasive alien species. According to records, water hyacinth was introduced to Taiwan from Southeast Asia in 1903. These aquatic plants all float on the water surface, and their growth and reproduction are closely related to the nutrient level in the water body. They reproduce sexually and asexually, and the speed of reproduction and diffusion is extremely fast. In recent years, the destruction of the ecological environment by the invasion of alien species has become one of the main reasons for the loss of...
