중금속(重金屬)(Cd)의 피해경감(被害輕減)을 위(爲)한 토양개량(土壤改良)에 관(關)한 연구(硏究) I. Cd침출(浸出)과 개량제(改良劑) 시용(施用)으로 인(因)한 치환성(置換性) Cd의 감소(減少)
Abstract
Effects of lime and ameliolating materials on decreasing available soil cadmium were studied, applying the amendments to Cd pre-and post-treated soils. Soil sttreated with Cd were placed in pots and kept under field moisture condition, summer through winter in 1981. The results of soil analysis made 40 to 60 days after the Cd treatment are as follows ; 1. Greater amount of Cd was extracted by 0.1N-HCl or 2% Citric acid than N-AcNH4 solution. More Cd was dissoluted by 0.1-HCl than 2% Citric acid. No Cd was extracted by pure water. Showing a wide variance in the amount of extractable Cd among treatments (amendments), the
카드뮴의 해독(害毒)을 경감(輕減)하는데 필요(必要)한 기초지식(基礎知識)을 얻기 위(爲)하여 카드뮴이 처리(處理)된 토양(土壤)에 석회물질(石灰物質)과 개량제(改良劑)를 사용(使用)한 것과 이미 석회(石灰)가 사용(使用)된 토양(土壤)에 Cd를 처리(處理)한 것을 분(盆)에 담아서 1981년(年) 여름 또는 가을에 자연토양수분조건하(自然土壤水分條件下)에 묻고 처리후(處理后) 40일(日)~70일(日)사이에 토양시료(土壤試料)를 채취분석(採取分析)한 결과(結果)는 다음과 같다. 1. 카드뮴은 토양(土壤)을 0.1N-HCl나 2%구연산으로 침출(浸出)했을 때에 많고,
