建立了流动注射-分光光度法在线测定水中铝离子的方法,经过优化实验条件,方法的线性范围为0.01～0.6 mg/L,检出限为0.004 mg/L。本法试剂消耗量少,分析速度快,灵敏度高,抗干扰能力强,适宜于现场的即时检测,回收率在97.7%～101.7%之间。 A flow injection - spectrophotometric method for on-line determination of aluminum ions in water was established. The optimized experimental conditions were linear in the range of 0.01-0.6 mg / L with a detection limit of 0.004 mg / L. This reagent consumes less, analysis speed, high sensitivity, anti-interference ability, suitable for on-site real-time detection, recovery rate between 97.7% ~ 101.7%.
