摘    要:通过大量的批实验来确定阿特拉津在不同土壤样本中的吸附参数,并对各土壤特性与吸附参数的相关性进行统计分析.结果表明,吸附参数仅与土壤有机碳含量极显著正相关,超过80%的阿特拉津吸附参数的空间差异可由土壤有机碳含量的空间差异来解释;吸附参数服从正态分布.方差分析表明,阿特拉津在土壤中的吸附表现出很强的空间差异,在不同地点的阿特拉津吸附参数无显著区别,而在不同的深度差别显著.

关 键 词:批实验  阿特拉津  吸附  有机碳  土壤

Abstract:A series of batch experiments were carried out to determine the sorption parameters of atrazine in different soil samples, and a statistical analysis was performed on the correlation between the characteristics of soils and the sorption parameters of atrazine. The results show that the sorption of atrazine by a soil was only significantly related to its organic carbon content. In other words, the organic carbon content of a soil was the most important factor affecting the atrazine sorption by the soil. More than 80% of the variability of atrazine sorption parameters could be explained by the variability of the organic carbon content in soils, and the sorption parameters were normally distributed. Variance analysis showed that the atrazine sorption by soils was of great spatial differences, and that there was no obvious difference in atrazine sorption at different locations, but the difference was obvious at different depths.
Keywords:batch experiment  atrazine  sorption  organic carbon  soil
