Reduction behaviors of pentavalent vanadium with biochar

  • 摘要: 针对钒化合物随价态升高毒性增加,且其对环境造成的危害也增大的现状,研究采用生物炭对其进行还原实现无害化处置。试验研究了生物炭用量、反应温度、硫酸浓度、反应时间等反应参数对钒还原率的影响。结果表明:五价钒在酸性条件下主要以VO2+、H3V10O283−和H2VO4的形式存在,在短时间内可以被生物炭还原成低价。在合适的反应条件下,即:钒的初始浓度为3 g/L,生物炭用量为3 g,反应温度为90 ℃,反应时间为60 min,硫酸浓度为20 g/L和搅拌转速为500 r/min,钒的还原率可达92.14%。在生物炭将五价钒还原的过程中不会引入其他杂质,该方法进行技术改良后在实现五价钒无害化的同时还可以用来制备低价钒化合物。
