Laboratory batch and soil column experiments have been conducted to elucidate the adsorption behavior of agrochemicals of low to high hydrophilicity. The results of this study can be summarized as follows. (1)Because none of the conventional techniques such as Gas Chromatography were suitable for the measurement of small amount of water samle less than 1ml obtainable by soil column experiments, complementary reverse-phase and molecular sieving HPLC technique were investigated to mesure agro-chemicals in ppb level without doing any extraction and concentration. (2)The adsorption capacity of soil increased with the increase of the concentration of the appropriate surface functional groups of soils. (3)Simple adsorption index predictable by infrared absorption spectroscopy together with our transport model thus allow one to estimate relative pesticide mobility over a wide range of soils and conditions with few measurement.

进行了实验室批量和土壤柱实验，以阐明低亲水性至高亲水性农用化学品的吸附行为。本研究的结果可总结如下。 (1)由于气相色谱等常规技术均不适用于土柱实验获得的小于1ml的少量水样的测定，因此研究了互补的反相和分子筛HPLC技术来测定农用化学品。 ppb 水平，无需进行任何提取和浓缩。 (2)土壤的吸附能力随着土壤适当表面官能团浓度的增加而增加。 (3)通过红外吸收光谱与我们的传输模型可预测的简单吸附指数，因此允许人们通过很少的测量来估计各种土壤和条件下的相对农药迁移率。
