生活饮用水中的氟离子(F-)、氯离子(Cl-)、亚硝酸根离子(NO-2)、硝酸根离子(NO-3)、硫酸根离子(SO2-4)等5种阴离子的国家标准检验方法均为化学法,操作费时,试剂消耗量大,特别是硫酸盐的测定更为复杂。我们用反相高效液相色谱法,20分钟内对
Five kinds of anion such as F-, Cl-, NO-2, NO-3 and SO2-4 in domestic drinking water The national standard test methods are chemical method, the operation time-consuming, reagent consumption, especially the determination of sulfate is more complicated. We used RP-HPLC within 20 minutes
