摘要
本文叙述了用真空减压蒸发法制备固体聚合硫酸铁的新工艺，对产品成分、红外光谱、差热曲线以及其溶解性和稳定性等特性进行了测试研究。研究表明，固体聚合硫酸铁与液体产品一样也具有良好的混凝性能和脱水效果。
In this paper a new process is described for preparing solid polyferric sulfate by means of vacuum depression vaporization. The product obtained was characterized by IR spectroscopy and differential thermal analysis, and its composition,solubility,stabiiity,etc. were researched. Acomparison with liquid products indicated that solid polyferric sulfate al- so displays a higher parification and dewatering of hydrolyzed residues.
