Carbon nanotubes (CNT) have been applied as adsorbent of solid-phase extraction (SPE) for preconcentration metal ions, because of the CNT's high surface area, excellent chemical, mechanical, thermal stability. In this paper, the achievements in study of using CNT as adsorbent of SPE for metal ions were summarized. The structure and characteristics of CNT were introduced in detail. The mechanism and application of CNT adsorption for metal ions were described with emphasis. The application potential of CNT as excellent adsorbent of SPE for metal ions was prospected.
