Abstract

The invention discloses a boron-doped ferro-manganese magnetic biochar material as well as a preparation method and application thereof. The preparation method of the boron-doped iron-manganese magnetic biochar material comprises the following steps: S1, providing biomass raw materials, namely FeCl3. 6H2O, MnCl2. 4H2O, H3BO4 and ultrapure water; s2, preparing the biomass raw material into powder; s3, dispersing the powdered biomass raw material in ultrapure water, then adding the FeCl3. 6H2O, the MnCl2. 4H2O and the H3BO4, and stirring to obtain a mixed solution; and S4, drying the mixed solution overnight, and then carrying out pyrolysis treatment to obtain a pyrolysis product. The ratio of the addition amount of the FeCl3. 6H2O to the addition amount of the MnCl2. 4H2O to the addition amount of the H3BO4 is 16.22 to 5.94 to 1. According to the preparation method disclosed by the invention, B atoms, Fe compounds and Mn compounds are doped into biomass raw materials, so that the boron-doped ferro-manganese magnetic biochar material is prepared. The prepared boron-doped iron-manganese magnetic biochar material has a good removal effect on pollutants, is high in applicability, has extremely high stability and reusability, and is an environment-friendly catalyst.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for preparing a boron-doped iron-manganese magnetic biochar material, and also to the boron-doped iron-manganese magnetic biochar material prepared by the preparation method, the boron-doped iron-manganese magnetic Application of ferromanganese magnetic biochar materials. Background technique [0002] The development of today's chemical industry is one of the important driving forces for the advancement of human society. However, harmful chemicals such as 4-chloro-3-methylphenol released into the environment during this process are difficult to degrade through conventional biological treatment processes. resulting in a persistent toxic effect on the environment. 4-Chloro-3-methylphenol is widely used as an important component of preservatives, disinfectants and fungicides, but it is also a toxic substance that is extremely harmful to humans and aquatic organism...
