Abstract

The invention provides a method for preparing a porous adsorption material from an oil shale semicoke stable Pickering emulsion. The method comprises the following steps: crushing oil shale semicoke,conducting screening with a 100-600-mesh sieve, performing calcining for 1-4 hours in a nitrogen atmosphere at 300-900 DEG C, dispersing the calcined oil shale semicoke into water, adding a functionalmonomer, a cross-linking agent and an initiator, performing uniform stirring, adding an organic solvent, performing stirring so as to obtain an emulsion, and performing polymerization for 4-24 hoursat 50-90 DEG C; after the reaction is completed, performing Soxhlet extraction for 12-48 hours by using acetone, and performing drying, so as to obtain the porous adsorption material. The porous adsorption material is prepared by taking the oil shale semicoke as Pickering emulsion stabilization particles and the emulsion as a template to polymerize the functional monomer in a continuous phase, isrich in internal pore structure, good in mechanical strength, good in adsorption effect on heavy metals, anion dyes and cation dyes, in addition, rapid in adsorption velocity, high in adsorption capacity and widely applicable to fields such as heavy metal pollution and dye wastewater treatment.

Description

technical field [0001] The present invention relates to a preparation method of a porous adsorption material, in particular to a method for preparing a porous adsorption material using oil shale semi-coke stable Pickering emulsion as a template, which is mainly used for the adsorption of anions / cations and heavy metal pollutants in the adsorption waste water , belonging to the technical field of polymer materials and the technical field of water treatment. Background technique [0002] Porous adsorption materials have very broad application prospects in the fields of water treatment and adsorption separation due to their rich internal pore structure, sufficient exposure of adsorption groups, and low mass transfer resistance. In particular, the porous materials constructed by the emulsion template method, whose porous structure can be adjusted through experimental parameters, the preparation process is simple, and the adsorption performance can be designed, have attracted ext...
