单点滴定与双点滴定铈量法测定Fe(Ⅱ)
Determination of Fe(Ⅱ) by single-point and double-point titrimetry using Ce4+ as titrant
【摘要】 以Ce4+标准溶液作滴定剂,用单点滴定法与双点滴定法对Fe(Ⅱ)的测定进行了研究。实验发现,在滴定分数α=0.9~1.0的条件下,单点滴定法有较高的准确度;在第一滴定点的滴定分数α≈0.9、ΔV=0.5~1.0mL的条件下,双点滴定法有较高的准确度。
【Abstract】 The determination of Fe(Ⅱ) was studied by singlepoint and doublepoint titrimetry using Ce4+ as titrant. The results showed that the measured error was small when α was 0.9~1.0 for the singlepoint titrimetry or when α1 was about 0.9 and ΔV was 0.5 mL~10 mL for the doublepoint titrimetry.
