A voltammetric method was developed for zirconium determination as Zr(IV)‐cupferron‐oxalate‐diphenylguanidine complex based on adsorptive accumulation at the HMDE (Epeak=−0.95 V). The supporting electrolyte was a mixture of acetate/acetic acid (pH 4.6) and ammonium acetate (pH 5.7) solutions.Eads=−0.6 V (vs. Ag/AgCl),tads=400 s, 10 mV s−1scan rate, and DP mode were the main parameters. The linear range was 0.033 to 3.3×10−9mol L−1, and theLODandLOQ(tads=400 s) were 0.77 and 1.6×10−11mol L−1, respectively. The method was adequate for seawater samples, although not sufficiently sensitive for surface waters.
