摘　　要：本文采用分光光度法对水中木质素和丹宁的含量进行测定,考察了Folin-Denis和Folin-Ciocal-teu两种试剂,通过比较确定采用Folin-Ciocalteu试剂,其在颜色稳定、防止沉淀生成和灵敏度等方面优于Folin-Denis试剂。In this paper,using spectrophotometry to mensurate the content of lignin and tannin,by comparing between Folin-Denis and Folin-Ciocalteu two reagents,Folin-Ciocalteu reagent,in the color stability,prevent precipitation and sensitive test is better than that of Folin-Denis reagent.
