摘要: 研究了聚合硫酸铁絮凝剂制备中亚铁的氧化反应速率.证明该速率对Fe2+,为零级.对NO2(g)为一级,因此提高气相中NO2的分压可大大缩短制备时间,Abstract: The Oxidation rate of ferros sulfate was investigated in preparation of PFSfloccu-lant. It was proved that this reaction is zero order with respect to Fe2+ and first order with respect to NO2 (g) .Therefore, if the partial pressure of NO2 (g) in gas phase is increased, the time needed for preparation will be decreased
