摘要
作者用自制的铂丝安培流通检测器,研究了测定钢铁中砷的流动注射分析条件,并利用萃取来消除干扰。减动注射方法比较简单,不包括前处理,分析速度是每小时150个样品,线性范围从5ppb到5ppm,溶液中检出限达到0.46ppb,相对标准偏差是1.02％。
Flow injection determination of arsenic in steel was made using a new home made platinum wire amperometric flow-through detector, interferences was removed by extraction. The flow injection method is simple with a vate of analysis 180 samples/h. The calibration curve had a linear range from 5 ppb to 5 ppm. The limit of detection was 0.46ppb(3σ) and the relative standard deviation was 1.02%(n=6).
