The extracted Cr (VI)-DPC complex is eluted with a mixture of methanol- sulfuric acid and quantified at 540 nm. The effect on the analytical signal and the optimization of variables were evaluated using multivariate and univariate techniques. A detection limit of 1 ng Cr (VI) and a linear working range of 3.2–600 ng Cr (VI) were obtained using a sample volume of 2 ml. The intra-day and inter-day RSDs were 4.8% (10 μg L−1, n=12) and 3.4% (n=5, different day with a different disk), respectively. The applicability of the fabricated 3D printed device has been proved by the determination of Cr (VI) in groundwater, surface water and leachates.
