Embodiment 1

[0023] Weigh 4g of macroporous strongly acidic cation exchange resin D001 into a 250mL Erlenmeyer flask, add 100mL of 0.02mol / L CuCl2·2H2O aqueous solution, shake at a constant temperature of 298K for 5h, and filter out the resin adsorbed with copper ions. Put the resin adsorbed with copper ions in a 100mL Erlenmeyer flask, add 50mL, 0.05mol / L Na2S 9H2O aqueous solution, shake at a constant temperature at 283K for 12h, filter out with a nylon filter cloth, wash with distilled water and ethanol three times alternately, 313K dry under conditions to obtain the nano-copper sulfide composite material 1. The solid loading amount of CuS in the composite material is 51.53mg / g. From figure 1 and figure 2 It can be seen from the comparison that there is no characteristic peak of copper sulfide in the nano-copper sulfide composite material 1, and no new strong characteristic peak appears, indicating that the supported copper sulfide is amorphous copper sulfide. From image 3 It can ...

Embodiment 2

[0028] Load 1 g of nano-copper sulfide composite material 2 into a jacketed glass adsorption column (Φ12×160 mm). The concentration of tetracycline in the influent water is 100mg / L, the pH value is adjusted to about 5, and the flow rate is 24mL / h through the glass adsorption column under the condition of 25±5°C, and the treatment capacity is 2000mL / batch. After being adsorbed by the nano-copper sulfide composite material 2, the average concentration of tetracycline in the effluent is <0.05mg / L.

[0029] When the adsorption reaches the leakage point (the immediate concentration of tetracycline in the adsorbed water is 2% of the influent concentration), the adsorption is stopped. At a temperature of 30±5°C, an aqueous solution containing 0.01mol / L sodium hydroxide and 10% ethanol is passed through the adsorption column to desorb and regenerate the composite material 2.

Embodiment 3

[0031] Weigh 4g of macroporous strongly acidic cation exchange resin D001 into a 250mL Erlenmeyer flask, add 100mL of CuCl2 2H2O aqueous solution with a concentration of 0.04mol / L, shake at a constant temperature of 290K for 5h, and filter out the resin with copper ions. Put the resin with copper ions in a 100mL Erlenmeyer flask, add 50mL, 0.1mol / L Na2S·9H2O aqueous solution, shake at a constant temperature at 280K for 12h, filter it out with a nylon filter cloth, wash it with distilled water and ethanol three times alternately, Dry at 313K to obtain nano-copper sulfide composite material 3. The CuS immobilization capacity of the composite material is 104.93 mg / g. Comparing the XRD pattern of nano-copper sulfide composite material 3 and the XRD pattern of D001 resin, it can be seen that there is no characteristic peak of copper sulfide in the synthesized nano-copper sulfide composite material 3, and no new strong characteristic peak appears, indicating that the The supported c...

Abstract

The invention provides an amorphous nano copper sulphide composite material, a preparation method and application thereof and relates to the field of environmental management. The composite material is composed of macroporous highly-acidic cation exchange resin and amorphous nano copper sulphide fixedly carried on the internal and external surfaces of the macroporous highly-acidic cation exchange resin; the preparation method comprises the steps: (1) adding CuCl2 aqueous solution, oscillating for 4-6 hours under the condition of 290-300K and filtering t obtain resin with copper ions; (2) adding Na2S solution to the resin with copper ions in the step (1), oscillating for 11-13 hours under the condition of 280-290K and filtering to obtain the amorphous nano copper sulphide composite material. The composite material has stronger absorption ability to antibiotic pollutants, does not loss during absorption and is easy to recover and regenerate.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to an amorphous nano-copper sulfide composite material, a preparation method and an application. technical background [0002] Antibiotics are a class of antibacterial drugs produced by microbial metabolism or artificially synthesized or semi-synthesized. Since its discovery, antibiotics have played a very important role in the treatment and prevention of human and animal diseases, as well as in promoting animal husbandry production, but a large number or even abuse of antibiotics has also brought a series of environmental problems. After humans and animals ingest antibiotics, they can only absorb a small part of them, and the rest are excreted in the form of original drugs or metabolites and enter the environment, causing a series of adverse environmental effects, such as the induction of "drug resistance genes" , cause poisonous damage to plants, destroy ecological balance,...
