Embodiment 1

[0029] Preparation of materials: First, the collected crab shells were calcined in air at 350°C to remove organic protein and chitin, and then ground into powder in a mortar. Using the combination of hard template and surfactant self-assembly method, the calcined crab shell powder was impregnated in the ethanol solution of hot sol and triblock copolymer P123. The impregnated composites were evaporated at 25°C for 6 h, and then further thermally cured at 100°C for 24 h to obtain calcium carbonate / solsol / P123 composites. The obtained composite was heated at 350°C under nitrogen atmosphere with a heating rate of 1°C min -1 P123 template was removed by pyrolysis for 2 h. Then, the composite material was heated at 900°C under a nitrogen atmosphere, and the heating rate was 5°C min. -1 Pyrolysis for 2 h for further carbonization. Finally, the obtained calcium carbonate / carbon composite was treated with (6 M) hydrochloric acid solution as the calcium carbonate template. After was...

Abstract

The invention relates to a preparation method of an ordered mesoporous carbon nanofiber array material and an application of the material in electrochemical sensing analysis of malachite green. The invention discloses the method for preparing the ordered mesoporous carbon nanofiber array material by using crab shells as a carbon source to carry out calcining in a nitrogen gas atmosphere. The preparation method provided by the invention is simple, is low in energy consumption, and has cheap and easily available raw materials, and the method for producing the functional material by utilizing environmental waste conforms to the national advocate of garbage classification and recycling. The prepared ordered mesoporous carbon nanofiber array material is used in electrochemical sensing analysisof malachite green, and rapid, sensitive and high-selectivity detection of malachite green is realized.

Description

technical field [0001] The invention belongs to the technical field of carbon material preparation and electrochemical analysis, and in particular relates to a preparation method of an ordered mesoporous carbon nanofiber array material and its application in a malachite green electrochemical sensor. Background technique [0002] Malachite green is a cationic triphenylmethane dye, which is widely used in cotton, wool, silk, paper, jute and other industries, because it has antibacterial, bactericidal and antiprotozoal effects, and is also used as a prohibited additive by criminals in fish farming industry, with serious negative impacts on public health and the environment [SACARA A, NAIRI V, SALIS A, et al. Silica-modified electrodes for electrochemical detection of malachite green [J]. Electroanalysis 2017, 29:2602 –2609]. At present, the more common detection methods of malachite green mainly include high-performance liquid chromatography (HPLC), molecularly imprinted micros...
