摘要
本文采用PT-C_18色谱预处理柱.以8-羟基喹啉为螯合剂,流动注射在线分离富集与原子吸收联机,成功地测定了环境样品中的铅.lmin富集(4.2ml)的检出限为7.5μg·l^(-1),相对标准偏差1.7%.
The method of preconcentration and determination trace lead in environmental samples by on line PT-C18 pre-column-FIA-AAS was described. By using 8-hydroxyquinoline as chelating agent,the detect limit was 7. 5μg ·1-1 per minute enrichment. Relative standard deviation was 0.017.
