Analcime/chitosan composite material and preparation method thereof and application of composite material as heavy metal adsorption material

The invention discloses an analcime/chitosan composite material and a preparation method thereof, and application of the analcime/chitosan composite material as a heavy metal adsorption material. Thepreparation method of the analcime/chitosan composite material comprises the following steps: firstly, preparing analcime by taking electrolytic manganese slag as a raw material; then, modifying the surface of analcime with chitosan so as to obtain the analcime/chitosan composite material which has uniform particles and is rich in micropores and mesopores. By adding the analcime/chitosan compositematerial into heavy metal wastewater, the purpose of quickly and efficiently adsorbing and enriching heavy metals can be achieved, the synthesis condition of the analcime/chitosan composite materialis simple, operation is convenient, and a new thought is provided for a resource utilization technology of solid wastes while the problem of electrolytic manganese residue pollution is solved. 本发明公开了一种方沸石/壳聚糖复合材料及其制备方法和作为重金属吸附材
