| 摘 要： | 水中天然(雌二醇,雌酮,雌三醇)与合成(炔诺酮,炔雌醇 )的环境雌激素经固相萃取柱浓缩净化,用二氯甲烷洗脱,经N,O 双(三甲基硅烷基)三氟乙酰胺(含 1%三甲基氯硅烷)衍生化后用气相色谱法进行测定.方法检出限在 8. 25~8. 99ng/L,相对标准偏差为 2. 1% ~8. 5%,加标回收率除炔雌醇较低外,其余均大于 80%.

| Abstract: | Natural (estradiol, estrone, estriol) and synthetic (norethisterone and ethinyl estra diol) estrogens in water were determined by GC. The estrogens were concentrated and purified on the SPE column, then eluted by dichloromethane, finally derived with N, O-bis(trimethylsilyl)trifluoroacetamide(BSTFA) containing 1 %trimethylchlorosilane(TMS). The detection limits were ranged from 8.25 ng/L to 8.99 ng/L, and RSDs were between 2.1 % and 8.5%. The recoveries were higher than 80 % except ethinylestradiol. |
