Abstract
This study was carried out to find a method to remove cadmium from soil and/or attenuate in Cd saturated Soil The chemical form of Cd was influenced by the physico-chemical properties of soil and the adsorption of Cd by soil conformed to the Langmuir isotherm. The order of Cd contents in chemical fractions extracted by several reagents was EDTA > NaOH >
중금속 오염(汚染) 농경지(農耕地)의 중금속 피해를 경감(輕減)하거나 제거(除去)하는 방안(方案)을 모색(摸索)하기 위하여 Cd 오염토양(汚染土壤)에 여러가지 이화학적(理化學的) 처리(處理)를 행(行)하고 연속분별추출법(連續分別抽出法)으로 Cd의 화학적(化學的) 형태별(形態別) 변화양상(變化樣相)을 분별정량(分別定量)하였다. 토양(土壤) 중(中)에 존재(存在)하는 Cd의 형태(形態)는 토양(土壤)의 이화학적특성(理化學的特性)에 따라 영향을 받았으며 흡착양상(吸着樣相)은 Langmuir식(式)에 부합(符合)되었다. 화학적(化學的) 형태별(形態別) Cd함량은
