摘要

研究了用Alconox、HCl和Na2 EDTA对臭椿叶片进行9种不同洗涤方法的颗粒污染物分析。对洗涤和未洗涤的叶片矿物进行了原子吸收光谱分析，对Ca、Mg、K、Na、Fe、Zn、Cu和Mn进行了分析，对Cl进行了特定离子电极分析，对Ti进行了分光光度法分析。结果表明，以1%乙醇手洗，再加入0.01 m Na2 EDTA，去除表面Fe、Cu、Zn和Ti的效果最好，叶片中K和Cl含量变化不大。

Evaluation of washing procedures for pollution analysis of Ailanthus altissima leaves

A study of nine different washing procedures using Alconox, HCl and Na₂ EDTA for use on Ailanthus altissima leaves in particulate pollutant analyses was conducted. Leaf mineral analyses of washed and unwashed samples were carried out for Ca, Mg, K, Na, Fe, Zn, Cu and Mn by atomic absorption spectrometry, for Cl by a specific ion electrode and for Ti by a spectrophotometric procedure. The data showed that a procedure consisting of washing by hand with 1% Alconox, followed by 0·01m Na₂ EDTA, was most effective in removing surface Fe, Cu, Zn and Ti and led to little change in leaf K or Cl.
