Anodio stripping neopolarography with rotating glassy carbon thin film mercury electrode has been carried out for the 1.fith order (e') and 2.5th order (e") differential eleotroanalyais. The general anodio stripping equations for the e'-E and e"-E curves have been derived and compared with those for e-E and m-E curves. Experimental results obtained with the inatrnment made in our laboratory are shown to be in good agreement with theory. This technique is much sensitive than that of anodio stripping voltammetry. Cadmium can be detected down to ppt level.
