Abstract
A method of manufacturing water-treatment particles comprises respectively preparing a particle-fabricating solution that comprises chitinous composition and a forming solution first. Next, a complex solution is prepared by adding calcium sulfite into the particle-fabricating solution. Finally, the complex solution is pumped into the forming solution to form water-treatment particles. In addition, water-treatment particles manufactured by the method above are also disclosed in the specification.
