| 中文摘要: |
| 研究了以二乙基二硫代氨基甲酸钠(DDTC)为络合剂、Triton X-100为萃取剂,应用浊点萃取-火焰原子吸收法测定环境水体中的微量元素镉的实验方法。探讨了影响浊点萃取的几个主要因素,并且实际测定了样品。在最佳实验条件下,Cd2+在0~10.00 μg/mL范围内呈良好的线性关系,相关系数r=0.999 5,方法的检出限为0.001 4 μg/mL,样品测定的加标回收率为95.56%~97.58%。 |
| 英文摘要: |
This paper is aimed at examining the application of CPE-FAAS in detection of trace cadmium in environmental waters , with diethyl dithio amino formic acid sodium (DDTC) as an complexing agent and Triton X/100 as an extractant, and dicussing several major factors affecting the cloud point extraction.
e samples are measured.
der the optimum experimental conditions, Cd2+ between the 0 and 10.00 μg/mL shows good linear relationship, the correlation coefficient r is 0.999 5, the detection limit of the method is 0.001 4 g/mL, and the recovery rate is 95.56%~97.58%. |
