A method for forming a chitosan membrane containing a nano-particle, comprising:
- providing a first feed comprising a chitosan;
- providing a second feed comprising A type zeolite or clay, wherein a dispersion process is performed to fabricate said second feed, and said dispersion process comprises an organic-acid aqueous solution to transform said A type zeolite or clay into a nano-particle and uniformly disperse said nano-particle, wherein said organic-acid aqueous solution comprises a pH about 1.8 to 3.4;
- performing a blending process to mix said first feed and said second feed, so as to form a mixture;
- performing an impurity removing process to remove impurities from said mixture;
- and
- performing a casting process for forming a chitosan membrane containing a nano-particle by said mixture with specific shape and thickness.
