摘要
采用吸光光度法研究藏茵陈提取液对NO2-的清除作用。研究了反应时间、溶液pH、提取液浓度和反应温度对NO2-的清除率的影响。实验结果表明:在pH=3,50℃,提取液浓度为5.56 mg/mL下反应30 min,具有最好的清除效果,清除率可达83%。
The clearance function to NO2-by extraction from Tibetan Capillaris was studied by spectrophotometry.The conditions’ in？ uence on the clearance to the NO2– was studied.The results showed that the optimum clearance of Tibetan Capillaris to the NO2– was at pH=3,50℃,25 mg/mL,reacted 30 min,the clearance rate can reach to 83%.
