Abstract

The invention provides preparation and application of a magnetic conductive polymer / sepiolite / humic acid composite microsphere, and belongs to the technical field of preparation of polymer nano composite materials. The preparation method comprises the steps of firstly mixing an aqueous solution of sepiolite with a humic acid aqueous solution, and adjusting the pH value of the mixed solution, so asto prepare a sepiolite / humic acid composite particle aqueous solution, mixing the sepiolite / humic acid composite particle aqueous solution with a magnetic ferroferric oxide cyclohexane solution, conducting shearing at a high speed to prepare a Pickering emulsion, then adding an aniline(pyrrole) monomer, conducting uniform dispersion, then slowly dropwise adding a hydrochloric acid solution in which an oxidizing agent ammonium persulfate is dissolved into the emulsion, collecting a reaction product, and conducting filtering, washing and drying, so as to obtain the magnetic polyaniline(polypyrrole) / sepiolite / humic acid composite microsphere. The preparation method is simple in preparation process and controllable in conditions, and the prepared magnetic polyaniline(polypyrrole) / sepiolite / humic acid composite microsphere has high adsorption characteristics and excellent environmental friendliness, and is suitable for the fields of industrial wastewater treatment and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer nanocomposite preparation, and in particular relates to a method for preparing magnetic polyaniline (polypyrrole) / sepiolite / humic acid composite microspheres for wastewater treatment. technical background [0002] With the development of modern industry, the demand for industrial water is increasing day by day, and the problem of water pollution is becoming more and more serious. Industrial wastewater is wastewater and waste liquid discharged during process production, mainly including inorganic wastewater, organic wastewater, heavy metal wastewater and radioactive wastewater. Among them, the hazards and toxicity of heavy metal wastewater and its application value in the recovery and utilization of metal resources are worthy of attention and in-depth research. [0003] There are many common treatment methods for heavy metal wastewater, including: ion exchange treatment, coagulation-flocculation, ...
