摘要
目的 :建立硒卡拉胶胶囊的含量测定方法。方法 :硒卡拉胶经氧瓶燃烧后生成无机硒 ,与 2 ,3-二氨基萘络合成 4,5 -苯并苯硒二唑 ,采用紫外分光光度法测定。结果 :硒在 0 2 0 7～ 2 0 6 7μg·ml- 1 范围内线性关系良好。胶囊的平均回收率为97 0 1% ,RSD =1 38% (n =5 )。结论 :该方法简便 ,准确。适用于硒卡拉胶胶囊的含量测定。
Objective:To establish a method for determination of selenium in k selenocarrageenan capsules.Methods:By oxygen flask combustion,k selenocarrageenan in k selenocarrageenan capsules can produce inorganic selenium,which combined with 2,3 diaminonaphthalene to form 4,5 benzopiaseleol,which in turn was determined by ultraviolet spectrophotometry.Results:The linear range for the determination of selenium was 0 207～2 067μg·ml -1 ,the average recovery of k selenocarrageenan capsules was 97 01%,RSD=1 38%(n=5).Conclusions:This method was simple and accurate,which could be used for determination of k selenocarrageenan capsules.
