Preparation method of halloysite-based molecularly imprinted nano material

The invention relates to the technical field of preparation of environmental functional materials, and provides a preparation method of a halloysite-based molecularly imprinted nano material and aimsto solve the problem of pollution caused by phthalate (PAEs) serving as a plasticizer at present. The method comprises the following steps of: purifying halloysite; preparing vinyl-modified halloysite; and finally, carrying out free radical polymerization on the surface of the halloysite by utilizing template molecules and functional monomers under the action of a cross-linking agent and an initiator to obtain the halloysite-based molecularly imprinted nano material. The material has the advantages of strong specific recognition capability on phthalate, high adsorption capacity and the like, can achieve the purpose of separating and enriching phthalate in water and food, and has a certain practical application value. 本发明涉及环境功能材料的制备技术领域，为解决目前塑化剂邻苯二甲酸酯(PAEs)的污染问题，本发明提出了一种埃洛石基分子印迹纳米材料的制备方法，包括埃洛石的纯化，制备乙烯基修饰的埃洛石，最后利用模板
