In our study, atomic layers of nickel were electrodeposited onto gold electrode within a few seconds. The nickel deposition was characterized by chronocoulometry and scanning electron microscopy. A simple method was developed for rapid and reliable determination of ultra-trace Ni by square-wave anodic stripping voltammetry. The key operational parameters of influencing the electroanalytical response of Ni, such as deposition potential, deposition time, and composition of the measurement solution, were investigated. Under the optimized condition, the detection limit was below 1 fg L��?1, which is the lowest ever reported for an electroanalytical technique and one of the lowest analytical methods for nickel determination.
