Abstract: An ultra-pure water manufacturing method using catalyst particles includes preparing first treated water by treating urea-containing feed water with urease-immobilized catalyst particles, and removing ionic substances from the first treated water by reverse osmosis, wherein the catalyst particles on which urease is immobilized are prepared by inducing a surface of the support to have an organic functional group thereon by modifying the surface of the support, coating a linker on the surface of the support, and immobilizing urease on the support in a buffer solution having a pH in a range of about 6 to about 8.
