유기점토를 이용한 다환방향족 오염물과 중금속의 흡착특성 연구
Abstract
The fate and the behavior of polycyclic aromatic hydrocarbons (PAHs) and heavy metals in the environment are mainly controlled by their interactions with various components of soils and sediments. Due to their large surface area and abundance in many soils, smectites may greatly influence the fate and transport of the contaminants in the environment. In our experiment, PAH sorption by hexadecyltrimethylammonium (HDTMA)-modified smectite linearly increased in proportion to the amount of HDTMA added on the clay. However, trimethylammonium (TMA)-modified smectite did not show superiority in its sorption of PAH compared with the HDTMA-smectite or dodecyltrimethylammonium (DTMA)-smectite. Meanwhile, the smectites modified with the same cationic surfactants adsorbed Cd
