目的：研究广西各类土壤对百草枯的吸附能力。方法采用高效液相色谱法,色谱柱：Kromasil C18柱(4.6 mm×200 mm,5μm)；流动相：乙腈-水(含0.03 mol·L-1庚烷磺酸钠、0.24 mol·L-1磷酸)=397(用三乙胺调pH至2.0)；检测波长258 nm；柱温25℃；进样体积20μL；流速0.8 mL·min-1。测定百草枯与4类土壤在3种介质中的峰面积,通过比较百草枯被土壤吸附前、后的峰面积,计算土壤对百草枯的吸附率。结果所检测的4种土壤对百草枯的吸附率均>99%。结论广西4类常见土壤可作为百草枯中毒急救的临时有效吸附剂。

Objective To study paraquat adsorbability of different field soils in Guangxi province of China. Methods HPLC method was adopted to measure the peak area of paraquat in three different media of four types of soils. Chromatographic column was Kromasil C18 column (4. 6 mm×200 mm, 5 μm); mobile phase was acetonitrile-water (including 0. 03 mol·L-1 sodium heptanesulfonate and 0. 24 mol·L-1 phosphoric acid) at a ratio of 397 (pH adjusted to 2. 0 by triethylamine). Detection wave length was 258 nm; column temperature was 25 ℃; the injection volume was 20 μL; flow rate was 0. 8 mL·min-1 . The peak areas of paraquat before and after being adsorbed were compared to calculate the adsorption rate of paraquat in different soils. Results All tested soil samples possessed the adsorption rate of paraquat over 99. 0%. Conclusion Four common field soils in Guangxi province can be used as temporary effective absorbents for the first-aid of paraquat poisoning.
