Abstract
A laboratory experiment was conducted to investigate the effects of pH, organic matters and anion on the adsorption and degradation of surfactant by different soils; Anmi series (limestone region), Gangseo series (alluvial soil). For this study, Alkyl Benzene Sulfonate (ABS ; Sodium Dodecylbenzenesulfonate) was used as a surfactant. The results were as follows: 1. Adsorption of ABS by soils was correlated positively with the equilibrium concentration of ABS in a soil suspension. (Anmi seris : r=0.9855, Gangseo series : r=0.9931). 2. Adsorption rate of ABS by soils was about 70% of the treated concentration (
토양중(土壤中)에서의 계면활성제(界面活性劑)의 분해(分解)와 pH, 유기물(有機物) 및 음(陰)이온이 토양(土壤)에 의한 계면활성제(界面活性劑)의 흡착(吸着)에 미치는 영향(影響)을 밝히고자 상이(相異)한 2개(個) 답토양(沓土壤)(안미통(安美統), 강서통(江西統))의 경작층(耕作層)에 대해 Dodecylbenzensulfonate(ABS)를 사용(使用)하여 실내시험(室內試驗)을 실시(實施)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 토양(土壤)에 의한 ABS의 흡착(吸着)은 ABS의 평균농도(平衡濃度)와 정(正)의 상관관계(相關關係)를 보여 주었다(안미통(安美統) r=0.9855, 강서통(江西統) r=0.9931). 2. 토양(土壤) 현탁액(懸濁液)의 pH가 4~5 일 때 토양(土壤)에 의한 ABS의 흡착(吸着)은 처리농도(處理濃度)(
