| 摘 要： | 采用离子色谱法测定选矿废水中微量F-、Cl-、NO3-、SO42-的含量。以SH-AC-1型阴离子分离柱为离子交换柱,以2.5 mmol.L-1碳酸钠-3.5 mmol.L-1碳酸氢钠溶液为淋洗液,采用抑制电导器检测。F-、Cl-、NO3-、SO24-4种阴离子分别在0.01~4.0,0.01~15.0,0.01~15.0,0.01~30.0 mg.L-1范围内呈线性关系,检出限(3S/N)分别为6.13,3.89,5.86,8.49μg.L-1。方法用于选矿废水试样中4种阴离子的测定,加标回收率分别为97.5%,104.0%,102.0%,98.3%,相对标准偏差均小于4.0%。
