dc.descriptionThis chapter deals with carbon and carbon nanotubes. Copper is one of a relatively small group of metallic elements that are essential for human, plant, and animal enzymes. Copper ions are introduced into human and animal bodies by food, water, air, etc. Copper enters the marine environment primarily from riverine transport and aerosols. Anthropogenic and geothermal sources can also be included. Depending on its concentration, copper may be a hazard to aquatic organisms. Nanomaterials based on only saturated carbon atoms, also known as carbon nanotubes, in both single-walled carbon nanotubes and multiwalled carbon nanotubes (MWCNTs), are becoming potential sorbents for metal ions due to their unique electronic, mechanical, and chemical properties. The aim of this work is to develop a reliable flow injection preconcentration system coupled to UV-V is molecular spectrophotometry for copper determination using MWCNT as sorbent.This system is the first one that demonstrates the powerful application of MWCNT in the field of solid-phase preconcentration using spectrophotometric determination, a technique naturally less selective than atomic absorption spectrometry. © 2010 Elsevier B.V.
