摘要
利用碱性氧化铝对葡萄酒脱色后,用分光光度法对其中高锰酸钾含量进行测定。在30℃、pH=8.5条件下,用4.0 g碱性氧化铝对20 m L样品进行振荡脱色2 h,脱色率可以达到95%以上,此法的测定准确度较高。
This paper presents a method for decolouring the wine by alkaline alumina,the content of potassium permanganate was determined by spectrophotometry. The decolouring condition was in 30 ℃and p H = 8. 5,4. 0 g alkaline alumina was used to decolour the solution for 2 hours, and the decolourization ratio was above 95%,and the accuracy of this method was high.
