Embodiment

[0041]A preparation method of Co / FeS / biochar composite material, comprising the following steps:

[0042] 1) Co(NO 3 ) 2 Dissolved in an organic solvent to obtain Co(NO 3 ) 2 solution, combining biochar with Co(NO 3 ) 2 The solutions were mixed, stirred for 4 hours, and dried at 80°C for 6 hours to obtain material A, wherein the organic solvent was ethanol, Co(NO 3 ) 2 Co(NO 3 ) 2 The concentration is 1mg / L;

[0043] The preparation method of the biochar is as follows: preparing pine sawdust as a biomass raw material, and crushing the biomass raw material to a particle size of <2mm. The pulverized biomass raw material was dried at 80°C for 12 hours, kept at 700°C for 2 hours under nitrogen atmosphere, washed with distilled water, and dried at 80°C for 12 hours to obtain biochar.

[0044] 2) Mix material A with FeS to obtain material B, put material B into the vacuum ball milling tank of the planetary ball mill, fill the vacuum ball milling tank with nitrogen, ball mi...

Abstract

The invention discloses a Co / FeS / biochar composite material and its preparation method and application. The preparation method comprises the following steps: adding Co(NO 3 ) 2 Dissolved in an organic solvent to obtain Co(NO 3 ) 2 solution, combining biochar with Co(NO 3 ) 2 Mix the solutions, stir for 4-12 hours, dry at 80-105°C for 6-12 hours to obtain material A, mix material A with FeS to obtain material B, and stir material B evenly under nitrogen or inert gas environment to obtain Co / FeS / biochar composite material, the Co / FeS / biochar composite material of the present invention realizes the efficient removal of artificial musk, compared with single material Co, FeS, biochar, the removal amount is from 83.7mg / g, 38.5mg / g , 25.4mg / g increased to 133mg / g. The ability to degrade pollutants has been significantly improved.

Description

technical field [0001] The invention belongs to the technical field of environmental functional materials and water treatment, and specifically relates to a Co / FeS / biochar composite material and its preparation method and application. Background technique [0002] Synthetic musk is a common PPCPs. Because of its strong fragrance, good aroma fixation and aroma enhancement effects, it is widely used in the perfume industry and pharmaceutical industry. Due to the high price of natural musk, after Baur and others first synthesized nitro musk at the end of the 19th century, artificial musk quickly became a cheap substitute for natural musk in the flavor and fragrance industry, and was widely added to various daily products (such as perfume, Soap, shampoo, shower gel, etc.) and some consumable products (such as insecticides, cigarettes, pesticides, explosives, etc.). Galaxolide (1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta-γ-2-benzopyran, HHCB) It is a typical semi-vo...
