【摘要】 本文通过对聚合硫酸铁（ＰＦＳ） 的动力学研究，发现ＰＦＳ的合成温度控制在５０ ℃以上就显著地提高了反应速度，缩短了反应周期。当相对水量Ｃ＝ ４ ．５ ～５ ．５ 时，采用工业级硫酸亚铁为原料，在催化氧化作用下，可以实现ＰＦＳ 的绝热合成工艺，去除加热设备，优化工艺过程。与直接氧化法ＰＦＳ相比，绝热法聚合硫酸铁（ＨＰＦＳ） 具有更优的混凝性能。更多还原

【Abstract】 The kinetic characteristic was studied in the synthetic process of polyferric sulfate (PFS). It is found that the synthesis temperature of PFS,if controlled more than 50℃,can apparently raise the rate of the synthetic reaction of PFS and shorten the reaction period. When the value of relative water C is equal to 4.5 ～ 5.5,under the oxidation of catalyst,the heat insulation synthesis of PFS is realized with the raw Fe 2SO 4·7H 2O,getting rid of the heating equipment and economizing the processing. The heat insulation polyferric sulfate (HPFS) has better coagulating effect than the directly oxidizing PFS.更多还原
