乙撑硫脲

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

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 .

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

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

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。
