Abstract: PURPOSE: An adsorbent for water treatment containing chitosan and a manufacturing method thereof are provided to increase adsorption quantity per unit volume while minimizing volume, and to improve intensity of chitosan and acid-resistance by manufacturing core-shell type chitosan beads. CONSTITUTION: An adsorbent for water treatment containing chitosan includes core-shell type chitosan beads. A manufacturing method of the core-shell type chitosan beads comprises the following steps: manufacturing chitosan liquid by adding chitosan powder with an ionic emulsifying agent, a carbon material, and an anionic enhancer in an acetate solution; manufacturing chitosan particles by adding a gelling solution in the chitosan liquid; and acquiring a shell membrane existing in the core of the chitosan particle.
