对Triad im efon在土壤中的降解和吸附行为进行了研究。两年的大田试验结果表明Triad im efon在红壤中半衰期分别为3.68d和8.77d,水稻土中分别为3.69d和7.63d,其降解受温度影响较大。批量法研究的Triad im efon在四种土壤中的吸附行为的试验结果表明Triad im efon在土壤中的吸附符合Freund lich经验公式;Kd随土壤有机质含量的增加而增大,吸附性与土壤有机质含量呈正相关;土壤有机质吸附常数Koc为259,表明Triad im efon在土壤中的移动性为中等:在土壤中的吸附量随温度的升高而降低,在土壤中的吸附主要为物理吸附。
Triad im efon in soil degradation and adsorption behavior were studied. Two years of field trials showed that Triad im efon had a half-life of 3.68 days and 8.77 days in red soil and 3.69 days and 7.63 days in paddy soil, respectively, and their degradation was greatly affected by temperature. The experimental results of Triad im efon batch adsorption study in four soils showed that Triad im efon adsorption in soil accorded with Freundlich empirical formula. Kd increased with the increase of soil organic matter content, and the adsorption and soil organic matter content The Koc of soil organic matter was 259, indicating that Triad im efon was moderately mobile in soil. The amount of adsorption in soil decreased with the increase of temperature, and the adsorption in soil was mainly physical adsorption.
