Problems solved by technology

[0003] However, commonly used adsorbents have disadvantages such as poor selectivity to specific antibiotics, low adsorption capacity, and susceptibility to environmental factors, which limits the application and development of adsorption technology in antibiotic wastewater treatment. Therefore, for specific clindamycin antibiotics, The research and preparation of new adsorbent materials need to be further strengthened, especially the lack of adsorbents for the adsorption and removal of clindamycin

Embodiment 1

[0050] (1) 500 grams of peanut shells are placed in a pulverizer to pulverize, and sieved with sieves with apertures of 4 mm and 6 mm respectively to obtain peanut shells with a particle size of 4 to 6 mm;

[0051] (2) Wash 75 grams of peanut shells obtained by step (1) with 420mL of deionized water and soak in 420mL of absolute ethanol for 1 hour, remove the liquid after filtration to obtain substance P, after substance P is washed with 350mL of deionized water To obtain substance P1, put substance P1 into 420mL of NaOH solution with a molar concentration of 3.3mol / L and soak for 1 hour, remove the liquid after filtration to obtain substance P2, and obtain substance P3 after substance P2 is washed with 450mL deionized water. Substance Q was obtained after being placed in a drying oven at 45°C for 24 hours;

[0052] (3) 10.99 grams of methyl sorbate are added to 1000 mL of ethanol solution with a mass percentage concentration of 25%, stirred for 3 minutes at 1000 r / min, shaken...

Abstract

The invention discloses a modified peanut shell adsorbent for adsorbing and removing clindamycin. The modified peanut shell adsorbent is prepared by the following steps: selecting peanut shells with a particle size of 4 to 6 mm, washing the selected peanut shells by using deionized water, absolute ethyl alcohol and a NaOH solution, and drying to obtain a substance Q; modifying the substance Q by virtue of a mixed solution prepared from methyl sorbate, thiodipropionicacid dilauryl ester, benzyl carbamate and sodium hydrosulfite to prepare a substance R; modifying the substance R by virtue of a mixed solution prepared from acetyl tributyl citrate, 2,5-thiophenedicarboxylic acid, 2-nitro-4-tertiary butyl phenol, 2-tertiary butyl-6-methylphenol, ammonium chloride, 2-phenylbenzimidazole-5-sulfonic acid and aluminate coupling agent to prepare a substance S; and modifying the substance S by virtue of a mixed solution prepared from cadmium nitrate, potassium borohydride, ferric nitrate and chromium nitrate to obtain a substance, i.e. the modified peanut shell adsorbent for adsorbing and removing the clindamycin.

Description

technical field [0001] The invention belongs to the technical field of adsorption treatment for antibiotic wastewater treatment, and in particular relates to a modified peanut shell adsorbent used for adsorption and removal of clindamycin. Background technique [0002] Antibiotic wastewater is a kind of high-concentration organic wastewater with deep color, high content of suspended solids, and high salt content. It has extremely complex components and has caused great harm to the environment. It has been listed by many foreign developed countries as a key environmental problem in the new era. The use of antibiotics will induce drug-resistant strains, and the continuous emergence of highly drug-resistant bacteria will seriously affect the ecosystem, cause toxicity to aquatic organisms, and threaten human health through food chain enrichment. Therefore, the management of antibiotics in the environment is particularly important. Antibiotics represented by clindamycin are broa...
