Direct photometric determination of lead by manual and flow injection methods with gallocyanine

Direct photometric determination of lead by manual and flow injection methods with gallocyanine

A direct photometric method was developed for the determination of sub-nanogram levels of lead. The method is based on complexation between lead and gallocyanin, which form a coloured dye (λmax 550 nm) at pH 8.0. The determination was based on the use of kinetic approach and in the lead concentratio...
