| Abstract: | The complexation of nitriloacetic acid (NTA) with copper and lead was studied by
square wave stripping voltammetry (SWSV) using a mercury iridium microelectrode as
the working electrode. The results show that NTA interfere with the measurements, but
if the mercury iridium microelectrode is coated with different concentrations of agarose
(0.75%, 1.5% and 15% w/v) this interference is greatly minimized. The best results
were obtained with 1.5% agarose. |
