Diphenylcarbazide coated cellulose materials combined with UV-VIS spectrophotometer were introduced as the simple detection method for quantitative determination of hexavalent chromium (Cr(VI)). The preparation of diphenylcarbazide coated cellulose materials was, first, cut cellulose materials into small pieces sized 1 cm x 1 cm, then, dip them into the 1,5-diphenylcarbazide solution (acetone) at the concentration of 0.04 M and, finally, evaporate the coated materials in air. For the calibration curve preparation, diphenylcarbazide coated cellulose materials were immersed in 25 mL of Cr(VI) solutions at pH 2 with concentrations ranging from 0 ug/L to 100 ug/L. The calibration curve obtained shows the relationship between the absorbance of Cr(VI)-diphenylcarbazide complexes and their concentrations. Additionally, the complex solutions developed different color shades starting from colorless to pink-violet color according to their concentrations. The detection limit could be obtained at the concentration of 1.43 µg/L with sufficient precision and accuracy. With this technique, color interferences from the presence of some salts, i.e., NO3-, SO42-, PO43-, Na+, K+, Mg2+, Cl-, Al3+, Cu2+, Zn2+, Pb2+ and Fe3+, did not occur at some particular salt concentrations with the Cr(VI) concentration at 100 ug/L. It could be concluded that the diphenylcarbazide coated cellulose technique is the simple detection method for Cr(VI) determination and could be applied to quantify the concentration of Cr(VI) in real samples, e.g., the extraction solution from plated-metallic sheet.
