Abstract:	自然界土壤通常無法對有機污染物與重金屬兼具高親和力，本研究群首先利用大型有機陽離子 (HDTMA)改質土壤以增加其對有機污染物的吸持能力，但受限於層隙構形往往使改質後之有機分佈介質難以達到預期效益。近年來有學者利用層狀矽酸鹽高表面積的特性，植入(Intercalation)不同大小的有機聚合物以剝離(Exfoliation)黏土礦物的層隙結構，製造所謂的“奈米矽片„並獲取不同理化特性的奈米微粒，但上述奈米矽片對環境中常見有機與無機污染物並不具親和力。基於上述認知，本計畫提出一個嶄新的理念，於層狀矽;Nature solids lack the ability of adsorbing organic contaminants and heavy metals simultaneously. In two decades ago, we had used that a high molecular organic compound with positive charge (HDTMA) absorbs on soil to enhance the SOM, which increases the a;研究期間：10408~10507
