砷钼杂多酸分光光度法测定三七中总砷含量
Determination of As in Panax notoginseng（ Burk. ) F.H. Chen by Heteromolybdoarsenic Acid Spectrophotometry
摘要
Abstract
[ Objective ] To obtain a rap( )termination method for arsenic from Panax notoginseng ( Burk. ) F. H. Chen. [ Method ] Content of As was determined by heteromolybdoarsenic acid spectrophotometry, and the developing conditions were optimized. [ Result] The optimum developing conditions were :color developing agent amount of 5.0 mi,color developing temperature of 40 ℃ and developing duration of 30 min.When the concentration of standard As Ⅲ solution ranged from 0 to 0.04 μg/ml, the linear relationship between concentration and absorbance was good (r =0.996 6). Arsenic was not detected in sample. [ Result ] High in precision and good in stability,the method can be used as the determination method for As from Panax notoginseng ( Burk. ) F. H. Chen.关键词
