A procedure for the preconcentration of copper was described in this paper using multi-walled carbon nanotubes (MWCNTs) oxidized by potassium permanganate as the adsorbent for the enrichment of trace copper in water samples.Important parameters, such as the sample pH, the concentration and volume of eluent, sample flow rate and volume, and interference of coexisting ions, were investigated.The obtained results indicated that proposed method possessed an excellent analytical performance.The linear range, the detection limit, and precison (RSD) were 1-100 ng/mL (R2=0.9993), 0.32 ng/mL and 2.88%, respectively.The results showed that copper could be adsorbed quantitatively on the pretreated MWCNTs with potassium permanganate, and proposed method was very useful in the monitoring of copper in the environment.
