EMBRITTLEMENT RESISTANCE EVALUATION METHOD OF ABSORBENT AND POWDER TRAPPING DEVICE USED FOR THE SAME

To provide a method for efficiently and rapidly evaluating embrittlement resistance of absorbent used for contaminated water treatment with sufficient accuracy.SOLUTION: An embrittlement resistance evaluation method of absorbent includes: (1) allowing a treated liquid to flow in a container storing absorbent; (2) acquiring a part of the treated liquid as a sample after starting the flowing; (3) evaluating the amount of particulates in the sample; and (4) evaluating the embrittlement of the absorbent on the basis of the amount of particulates.SELECTED DRAWING: Figure 3 【課題】汚染水処理において用いられる吸着材の耐脆化性を、十分な精度で、効率よく且つ迅速に評価する方法を提供する。【解決手段】（１）吸着材を収容した容器中で、被処理液を流動させ、（２）流動開始後に被処理液の一部を試料として取得し、（３）試料中の微粒子量を評価し、（４）微粒子量に基づいて、吸着材の脆化を評価することを含む吸着材の耐脆化性評価方法。【選択図】図３
