Hexavalent chromium reduction using iron powder has the advantages of being efficient and capable of degrading pollutants, as well as inexpensive and simple to procure. The performance of a new rotating fixed-bed batch reactor in treating aqueous solutions containing chromium hexavalent ions with iron powder was investigated. Two magnets were covered with iron powder and coupled with an isolated stainless-steel shaft in a new agitator design. Variables such as time, initial hexavalent chromium content, iron powder dose, rotational speed, and pH were investigated in order to discover the optimum chromium removal approach. The analysis of variance (ANOVA) was used to determine the experimental kinetics. Contact time of 21 minutes, initial Cr(VI) concentration of 30 ppm, iron powder dosage of 10 g, rpm of 276 and pH of 3 were determined to be the optimal conditions for removing hexavalent chromium.
