Abstract:Magnetic Fe3O4 and polyaniline nano-composite (MPN) was prepared and used for reduction of highly toxic Cr(VI) to low toxic Cr(III) ion. The effects of various parameters such as synthesis proportion, solution pH and initial Cr(VI) concentration on the efficiency of reduction process were investigated. Results showed that a high concentration of Cr(VI) solutions(10mg/L, 50ml) can be efficiently (>= 99%) reduced by MPN(0.01g). Decreasing of solution pH increased the performance of reduction process.
