众所周知,乙醇是试剂制备、有机化工、高分子合成、制药工业以及各项科研事业中重要的溶剂和原料之一。在生产和贮存过程中,由于种种原因,乙醇常会受到铁的污染。在物质制备中,含铁乙醇不仅会使产品的性能变坏,而且会引起一些催化剂的严重中毒,从而导致产率下降。对于含铁乙醇的处理,常用的方法是蒸馏。但蒸馏须耗用较多热量,因此促使人们去研究能节省能耗的替代方法。我们在研究MnO_2粉末对水溶液中铁的动态吸附作用的基础上,又研究了MnO_2粉末在乙醇-水
It is well known that ethanol is one of the important solvents and raw materials in reagent preparation, organic chemistry, polymer synthesis, pharmaceutical industry and various scientific research. During production and storage, ethanol is often contaminated with iron for various reasons. In material preparation, ferric ethanol not only deteriorates the performance of the product but also causes severe poisoning of some of the catalysts, resulting in a decrease in yield. For the treatment of ferrous ethanol, the usual method is distillation. However, distillation requires more calories, prompting people to study alternative ways to save energy. On the basis of studying the dynamic adsorption of iron in aqueous solution by MnO_2 powder, we studied the effect of MnO_2 powder in ethanol-water
