In this study, modified electrodes based on reduced graphene oxide modified with iron (II) phthalocyanine or nickel (II) phthalocyanine were used for determination of lead in different types of water samples using differential pulse anodic stripping voltammetry. The lowest limits of quantification obtained, were 0.001035 µg L −1 for the modified electrodes, and 0.00207 µg L −1 for unmodified electrodes, with a correlation coefficient (R 2 ) between 0.996 and 0.997. The results obtained for the
