石墨炉原子吸收法测定生殖液中铅和镉含量的方法研究

Study of Determination Method for Lead and Cadmium in the Semen and Liquor Follicle of Genetic Fluid

就体液中金属元素的测定方面而言,对生殖液的研究则相对较少.文章建立了测定精液和卵泡液中铅和镉的简洁可靠的方法,对样品的处理、基体改进剂的选择、样品的用量、测定参数的选择等方面进行了研究,方法对铅的加标回收率在99.0%～118%之间,对镉的的加标回收率在96.3%～109%之间.方法的最低检出浓度为铅0.8μg·L-1,镉0.05μg·L-1.相对标准偏差在3.74%～8.54%之间.

Lead and Cadium as the key elements influencing human genetic health were selectively determined in the present paper. In the area of metal elements determination in body fluid, most samples used in the study are blood, plasma and saliva. No literature about genetic fluid determination has been found so far. In the present paper the preparation of samples, volume of samples, and determination parameters were investigated. An easy reliable method of determining lead and cadium in semen and liquor follicle is established. The recoveries of lead are 99.0%-118% and the recoveries of cadium are 96.3%-109%. The determination limit of lead is 0.8μg·L^-1 and the determination limit of cadium is 0.05μg·L^-1. The relative standard deviations （RSD）（ n = 5）are 3.74 %-8.54 %.
