| 摘 要： | 采用微波消解对天然棕色棉和染色棕棉样品进行处理,通过电感耦合等离子体发射光谱法和电感耦合等离子体质谱法测定其中B、Na、Mg、Al、P、K、Ca、Ti、V、Mn、Fe、Co、Ni、Cu、Zn、Ga、Se、Rb、Sr、Mo、Ag、Cs、Ba、U等24种元素的含量。结果表明,与染色棕棉相比,天然棕色棉中B、Mg、P、K、Ca、Ti、V、Mn、Rb、Mo等元素含量显著偏高(P0.05),Na元素含量显著偏低(P0.05),采用聚类分析(最短距离法)对样品中24种元素含量进行处理,可正确判断天然棕色棉和染色棕棉。

| Abstract: | The content of B,Na,Mg,Al,P,K,Ca,Ti,V,Mn,Fe,Co,Ni,Cu,Zn,Ga,Se,Rb,Sr,Mo,Ag,Cs,Ba,U in naturally brown cotton and dyed brown cotton were determined by the means of ICP-OES and ICP-MS coupled with microwave digestion.Compared with those in the dyed cotton,the content of B,Mg,P,K,Ca,Ti,V,Mn,Rb,Mo in naturally brown cotton samples were significant higher (P＜0.05),while the content of Na in naturally brown cotton samples was much lower (P＜0.05).The single linkage method of cluster analysis was applied to evaluate 24 elements in all the samples,which exhibited the ability to effectively differentiate the naturally brown cotton samples from dyed colored samples. |
