Pre-concentration and determination of Pb(II) from water samples using modified multiwalled carbon nanotubes

Pb(II) is a topically poisonous metal ion that can affect almost every organ and system in the body; it can accumulate in the body and cause kidney malfunctioning, hematological and brain damages. Recently, carbon nanotubes (CNTs), the nano-structured material, are applied for pre-concentration of h...
