Abstract

The invention discloses a monstera deliciosa adsorbing material and a preparation method thereof. The preparation steps are as follows: fresh monstera deliciosa without roots is first soaked in water containing sodium thiosulfate, methanol and acetic acid are then constantly added into the solution, and after the monstera deliciosa is kept for 15 to 30 days, the nearly silt-like monstera deliciosa is then dried and loaded into a chromatographic column, washed with acetic acid, fumaric acid and ketoglutaric acid, soaked in trimethylstearylammonium bromide solution, then carbonized under the conditions of nitrogen protection and high temperature, cooled to the room temperature and finally ground. Different from modification by way of soaking, acidification, activation and the like, the invention utilizes the function of microorganisms to change the surface properties of the adsorbent, and attaches polycarboxyl compound and polyhydroxy compound on the surface of the adsorbent, so that the properties of the adsorbent are further enhanced and the adsorbing capability of the adsorbent is better.

Description

technical field [0001] The invention relates to a monstera adsorption material and a preparation method thereof, belonging to the field of material preparation. Background technique [0002] The monstera plant is small and exquisite, which is a perennial evergreen vine-like herb with bright green leaves and a chic plant shape, especially the closely arranged holes on the leaves, which are like skylights opened, which are particularly novel, unique, elegant and unique. Ideal plant species for decoration. [0003] Although there are a variety of adsorbents on the market at present, there are more or less deficiencies, so it is very necessary to modify the adsorbent materials to a certain extent. For example, in a "Research on Fly Ash Modified Adsorbent Materials" proposed by the Department of Chemical Engineering of Xiangtan Institute of Technology, the specific surface area of ​​the zeolite-like adsorbent prepared by calcining Na(OH)2 solution and the new Inner Mongolia fly ...
