摘　　要：研究了以碳酸铈和乙酸为主要原料,合成硝酸铈铵和乙酸钠的集成工艺。讨论了前驱体氢氧化铈的硝酸溶解性能、硝酸铈铵结晶母液的循环利用、结晶母液中铈的回收方法。从原料碳酸铈到最终产物硝酸铈铵,铈的总收率为95.61%。以硝酸铈铵为引发剂,引发了丙烯酸与壳聚糖的接枝共聚反应,接枝率为45.69%。An integrated technology for ammonium ceric nitrate and sodium acetate with cerium carbonate and acetic acid as main raw materials is reported. The solubility of the precursor ceric hydroxide in nitric acid, recycle of crystal mother liquor of ammonium ceric hydroxide, and recovery method for cerium in mother liquor have been investigated. From the raw material cerium carbonate to the product ammonium ceric nitrate, the cerium total recovery is 95.61%. Graft co-polymerization of acrylic acid onto chitosan is carried out by ammonium ceric nitrate as an initiator, and its grafting percentage is 45.69%.
