摘要
通过对2.6-二氯酚靛酚滴定法和紫外吸收法测定维生素C的比较研究,发现紫外吸收法抗干扰性强,回收率高,在0～80μg/ml范围内线性较好,测定过程中较稳定,特别对于有颜色样品更优于滴定法。
This paper describes comparative studies that the twomether ofultraviolet absorption and 2,6-Dichlor-phenclindophenol titration in determinatior of the content of vitaminC. The results shows that the former was powerful in resisting interference and had a higher recollect rate than the latter, and it was good direct reaction within 0 - 80μ/ml, and stabler in determination. Especially for the colour sample, the former was better than the latter.
