Abstract: The present invention relates to a pre-filter for removal of cesium and a method of manufacturing the same. The pre-filter for removal of cesium includes ultra-high-molecular-weight polyethylene and a cesium adsorbent, and is manufactured in which the ultra-high-molecular-weight polyethylene and the cesium adsorbent are mixed, heated, and molded or the ultra-high-molecular-weight polyethylene and the cesium adsorbent are mixed, molded, and heated. The pre-filter manufactured thereby removes cesium excellently and has excellent impact resistance, abrasion resistance, slipperiness, and chemical resistance.

Abstract: The present invention relates to a carbon block filter for removal of cesium and a method of manufacturing the same. The carbon block includes activated carbon, a binder, and a cesium adsorbent, and is manufactured in which the activated carbon, the binder, and the cesium adsorbent are mixed, heated, and molded or the activated carbon, the binder, and the cesium adsorbent are mixed, molded, and heated. The carbon block filter manufactured thereby removes cesium excellently and maintains water purification performance for long periods of time.
