Efficient analysis of Cr(VI) samples is important for the environment and for metal finishing industries. For this study, microplate assay was applied for Cr(VI) analysis using diphenylcarbazide for rapid and simultaneous analyses of multiple samples. Results demonstrated that the microplate assay can also detect Cr(VI) at concentrations below the effluent standard. Furthermore, the assay has high measurement repeatability and good agreement with the official assay method.
