Si multaneou s Determination of herbicides in Water Using M ulti-Walled Carbon N anotubes and chem ometrics Methods

Many research works focuse d on the detection of su lfonylurea herbicides at trace level, and achiev ed many valuable analy tical techni ques [۱-۳]. S olid phase extraction (S PE) has be en the most important technique u sed for trac e enrichment of sulfonylurea herbicides in water samples. In recent years, m ulti-walled carbon nanotubes (M WCNTs), was successfully observ ed and ab orbed mor e attentions due to its advantage that can b e used for many differe nt goals in terms of its special chemical and physical properties. The goal of this study is to i nvestigate th e optimum trapping capability of MWCNTs fo r the sulfonylurea herbicides using chemometrics methods. In this work, two environmental water samples were use d for evalua tion including well water (east Teh ran town), river water (Jajerood).
