  1. 顶空气相色谱法测定大白菜中的乙撑硫脲

    Determination of ethylenethiourea in Chinese Cabbage by head space-gas chromatography

  2. 建立了一种采用高效液相色谱仪测定乙撑硫脲(ETU)在西瓜、瓜叶和瓜田土壤中残留量的分析方法。

    A determination method of ethylene thiourea ( ETU ) residue in watermelon , watermelon leaf and soil by high performance liquid chromatography ( HPIC ) has been established .

  3. 代森锰锌废水中乙撑硫脲的高效液相色谱分析

    Quantitative Analysis of ETU in Mancozeb Waste Water by HPLC

  4. 西瓜、瓜叶及瓜田土壤中乙撑硫脲残留量的液相色谱分析方法研究

    Study on Determination Method of ETU Residue in Watermelon , Watermelon Leaf and Soil by HPLC

  5. 本文采用雷尼镍催化剂吸附乙撑硫脲中的硫,生成硫化镍,加入浓盐酸,使硫化镍全部转化为硫化氢,通过气相色谱测定顶空气体中硫化氢的含量,可间接测定乙撑硫脲的含量。
