本文推荐一种简便、快速测定血中镉的分析方法。在水和血液的基体中加入改进剂铂,分别使样品灰化温度提高到900℃和600℃而不发生镉的损失。而且可直接用含铂水溶液冲稀样品,直接进样石墨炉(10微升),进行镉的吸收测定。该方法的灵敏度为0.03ppb,相对偏差0.048,检出限为0.10ppb,平均回收率为95％～108％。和文献取得一致的结果。可应用于临床化验和环境监测。
This article recommends a simple and rapid method for the determination of cadmium in blood. In the water and blood matrix to improve agent platinum, respectively, the sample ashing temperature increased to 900 ℃ and 600 ℃ without the loss of cadmium. And can be directly diluted with platinum aqueous solution diluted samples directly into the graphite furnace (10 μl) for cadmium absorption determination. The sensitivity of this method is 0.03 ppb, the relative deviation is 0.048, the detection limit is 0.10 ppb, and the average recovery is 95% -108%. And the literature achieved the same result. Can be applied to clinical laboratory and environmental monitoring.
