Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the following description is only for explaining the present invention and not limiting its content.

[0034] 1. Preparation of banana stem activated carbon:

[0035] (1) Pretreatment of banana stems: wash the banana stems with water to remove surface dust and impurities, dry, pulverize, and pass through a 100-mesh sieve to obtain banana stem powder;

[0036] (2) Impregnation: The above-mentioned banana stem powder and the phosphoric acid solution with a mass fraction of 70% were impregnated at room temperature for 12 hours according to the ratio of material to agent of 1:5;

[0037] (3) Activation: the soaked banana stem powder was activated at 450° C. for 75 minutes.

[0038] (4) Cleaning and drying: After the activated banana stem activated carbon is cooled, it is repeatedly cleaned with deionized water, and the residual phosph...

Abstract

The invention discloses an application of banana stem activated carbon in adsorbing amoxicillin. The banana stem activated carbon as an adsorbent adsorbs amoxicillin in absorbed water. The waste banana stems as a raw material are turned into wealth, so that comprehensive utilization of wastes and the environmental protection are facilitated, the raw material source of the activated carbon is alsoexpanded, and the production cost of the activated carbon is reduced. The specific surface area of the banana stem activated carbon is 1177.03 m<2> / g, the total pore volume is 1.90 cm<3> / g, the micropore volume is 0.38cm<3> / g, and the mesopore volume is 1.52 cm<3> / g. The highest removal rate of amoxicillin in water can reach 90%, and the banana stem activated carbon has a very good application prospect for solving the problem of purifying treatment of antibiotic wastewater.

Description

technical field [0001] The invention relates to an application of activated carbon, in particular to an application of banana stem activated carbon in adsorbing amoxicillin. It belongs to the application field of activated carbon. Background technique [0002] In the context of vigorously developing green chemistry and green agriculture, actively developing the secondary utilization of agricultural sideline activated carbon is the pursuit of the times. At this stage, the activated carbon manufacturing industry has begun to eliminate ZnCl 2 Activation method to prepare activated carbon, to H 3 PO 4 The activation method is moving closer. According to the latest statistics, in 2016, the harvested area of ​​bananas worldwide was 4.3497 million hectares, with an output of 7,024 tons. Among them, the Asian country with the largest harvested area and output is India, with 588,100 hectares and 14.84 million tons, accounting for 13.64% of the world respectively. and 23.74%; foll...
