聚合氯化硫酸铁的合成

Synthesis of Ferric Sulfate Polychloride

以硫酸亚铁为原料，氯气为氧化剂，氢氧化钙和稳定剂为中和剂，当溶液ｐＨ值为１．９０～２．００，氧化时间为０．５ｈ，铁离子质量浓度为０．０８ｍｏｌ／Ｌ时，可以合成盐基度为５６％的聚合氯化硫酸铁，液收为７５％

Using ferrous sulfate as raw material, chlorine as oxidant, calcium hydroxide and stabilizer as neutralizer, when solution pH value is 1.90～2.00, oxidation time is 0.5 h and mass concentration of ferric ion is 0.08mol/L, can synthesize ferric sulfate polychloride with salinity of 56% and solution yield rate is 75%.
