The authors of “Electrocatalytic oxidation and amperometric determination of hydrazine using a carbon paste electrode modified with β-nickel hydroxide nanoplatelets (Microchimica Acta (2019) 186:441)” wish to update the incorrect panel/labels of Fig. 3. Unfortunately in the online version of the article, Fig. 3 has four parts which should be labeled as a, b, c, and d; but were incorrectly labeled as a, b, d, and d. There are two “d” in and no “c”. The correct image is given in this article.

a Cyclic voltammograms of NP-CPE recorded at different potential sweep rates of 1–600 mV s−1. b Linear dependency of anodic and cathodic peak currents on the potential sweep rates at values lower than 20 mV s−1. c Dependency of anodic and cathodic peak currents on the square root of the potential sweep rate at high values of ≥30 mV s−1 d Variation of the anodic and cathodic peak potentials with the natural logarithm of the potential sweep rate
