The preparation technique of zinc exchanged zeolite antibacterial material for environment decontamination is investigated in the paper. A intermediate of the antibacterial material with 5.56wt% exchanged Zn2+ is obtained by optimizing all the relevant factors, and the stabilizing treatment of the material has also been carried on so as to control the solution speed of Zn2+. The test for the antibacterial performance of the material shows that the bactericidal rate for bacterium coli and staphylococcus can reach 99% under the condition of MIC=500mg/ml, and the absorbability of the material for small polar molecules is also pretty strong so as to be used for moisture absorption, deodorization and decontamination indoors. The antibacterial mechanism and the application of the material have also been discussed in this paper.
