Abstract:

T he common resuscitative agent for polluted cation ex-change resin by iron is hydrochloric acid.In order to fully resuscite, the percentage of hydrogen chloride in hydrochlo-ric acid is as high as 10%.This paper introduces a mixed solution of HCl-NaCl-Na₂SO₃ as resuscitative agent, in which these percentages of components are 4%, 4% and 0.08% respectively.

Key words: resuscitativc agent, polluted cation exchange resin, hydrochloric Acid, sodium chloride, sodium sulfite

摘要：

铁污染软化水用树脂常用复苏剂是盐酸。为使树脂充分复苏，需用浓度高达10%HCI溶液浸泡树脂。作者用氯化氢-氯化钠-亚硫酸钠混合溶液作复苏剂，各组份浓度依次为4%、4%、0.08%,能快速使树脂充分复苏。酸浓度低、腐蚀性弱，对国内现有的小型软化水系统更为适用。
