A novel, simple, cost-effective, and sensitive method was developed for the ‎determination of metal ions in water samples using multi-walled carbon Nanotubes as ‎solid-phase adsorbents coupled with hollow fiber liquid phase microextraction. In this ‎research a simple microextraction method was applied for the pre-concentration and ‎extraction of metal ions from water samples. We used of octanol, as a liquid phase, and ‎multi-walled carbon Nanotubes (MWCNTs) as the solid phase which both were ‎impregnated into the pores of polypropylene hollow fiber as a solid/liquid ‎microextraction device for extraction of metal ions from water samples. For optimization ‎of the method different parameters such as; kind of organic extractor solvent, extraction ‎time, agitation speed and pH were monitored and controlled. The effect of oxidation on ‎the structural integrity of multiwalled carbon nanotubes through different agents has been ‎studied. For these purpose, multiwalled carbon Nanotubes (MWCNTs) were ‎functionalized by different agents like; nitric acid, citric acid and KMnO4 (PP) solutions. ‎Here also the functionalized MWCNTs were sonicated in octanol and then injected into ‎the porous hollow fiber tube. The method was evaluated and finally applied to waste ‎water sample and results were obtained. All microextraction experiments were carried out ‎at room temperature, 25oC.‎
