在碱性介质中,甲巯咪唑能强烈增敏纳米-鲁米诺-硝酸银化学发光体系产生较强的化学发光信号,据此建立了一种流动注射化学发光测定甲巯咪唑的新方法.在优化实验条件下,该方法对甲巯咪唑的检测线性范围为1.0x10-9～1.0 x 10-8、1.0x10-8～ ...在碱性介质中,甲巯咪唑能强烈增敏纳米-鲁米诺-硝酸银化学发光体系产生较强的化学发光信号,据此建立了一种流动注射化学发光测定甲巯咪唑的新方法.在优化实验条件下,该方法对甲巯咪唑的检测线性范围为1.0x10-9～1.0 x 10-8、1.0x10-8～ 1.0 x 10-7、1.0x10-7～1.0x10-6 g/mL,检出限（S/N=3）为3.0x10-10 g/mL,相对标准偏差为1.2％ （n=11,ρ=1.0x10-8g/mL）.将该法用于药物中甲巯咪唑含量的测定,结果满意.同时。展开更多
文摘以石墨板为工作电极(阳极、阴极),碎屑状铁颗粒作为填充电极,自制三维电极-电Fenton反应器对模拟氨氮废水进行处理,考察不同电压、初始p H值、铁粉加入量、曝气等因素对模拟废水中氨氮去除效果的影响。结果表明,p H为6左右,加入1 g/300 m L Fe粉,15 V电压下1.5 L/min的曝气下电解60 min后,炼油废水的NH3-N的去除率达到最佳。
