Highly Efficient Reduction of Cr (VI) with C4H6O6
In this paper, tartaric acid (C<sub>4</sub>H<sub>6</sub>O<sub>6</sub>) was used as a reductant to treat chromium (VI)-containing solution. Several independent experimental parameters, including reaction temperature, concentration of H<sub>2</sub>SO<sub>4</sub>, concentration of C<sub>4</sub>H<sub>6</sub>O<sub>6</sub> and reaction time, on the reduction process were studied. The results showed that 100% of the Cr (VI) could be reduced by C<sub>4</sub>H<sub>6</sub>O<sub>6</sub> in a strong acidic environment under a high reaction temperature. All of the experimental parameters showed positive effects on the reduction process and followed the order [H<sub>2</sub>SO<sub>4</sub>] > [C<sub>4</sub>H<sub>6</sub>O<sub>6</sub>] > reaction temperature > reaction time. A higher concentration of tartaric acid and higher reaction temperature could facilitate the reduction process and reduce reaction time.
