| 中文摘要 |
| 采用逆流流动注射在线萃取,用APDC+DDTC为络合剂,MIBK作萃取剂,与火焰原子吸收光谱仪联用测定Cu、Fe、Pb、和Mn的灵敏度,分别提高了35.7、34.3、48.7和41.6倍,检测限分别为1.6、7.5、3.3、2.1μg/L.该法用于含这些重金属很低的饮用水和环境水样的测定,获得了满意的结果。 |
| 英文摘要 |
| FAAS with reverse flow injection analysis technology of on line extraction was used to make the determination of trace Cu,Fe,Pb and Mn in drink water and environmental water.APDC and DDTC,MIBK were used as chelating,extracting agent respectively.The sensitivity of determination increase 35.7, 34.3,48.7and 41.6 times for Cu,Fe,Pb and Mn respectively.The detection limits for Cu,Fe,Pb and Mn are 1.6, 7.5, 3.3 and 2.1μg/L respectively.The results are satisfactory. |
