摘要 用3 mol/L硫酸溶液溶解样品,(NH4)2Fe(SO4)2作为还原剂,K2Cr2O7作为氧化剂,利用间接氧化还原法测定CexZr1-xO2-δ固溶体的氧缺陷值δ,方法的相对标准偏差为1.3%. The oxygen deficiency in the CexZr1-xO2-δ solid solution was determined by indirect redox-titrimetry after dissolving the solid sample in 3 mol/L sulphuric acid. （NH4）2Fe（SO4）2 was used as a reducing agent and K2Cr2O7 as an oxidizing agent. The relative standard deviation of the method was 1.3 %.
