Butylated hydroxyamsole (BHA) and other tocopherols are shown to accumulate very strongly onto carbon paste, with the surface species retaining their characteristic electroactivlty. This accumulation serves as a preconcentration step which improves the voltammetric measurement with respect to the se
In this paper, the analytical performance of a AIPO, containing chemically modified electrode (CME) for Pb2+ preconcentration and quantitation will be discussed. The electrode employed was prepared simply by the addition of an appropriate quantity of sparingly soluble AIPO, as a modifier to a conven
