【摘要】 应用石墨炉原子吸收光谱法测定小白鼠生物样本中的铂含量进行了研究。通过二步灰化法与塞曼背景扣除法相结合,较好地解决了生物样本中的背景干扰问题,测定尿样的相对标准偏差为3.00%、肾皮质部消化液相对标准偏差为5.26%、血清相对标准偏差为9.42%,简化了测定程序,建立了对小白鼠尿、血清、肾皮质部消化液等生物样本均有较好适应性的痕量铂的测定方法。更多还原

【Abstract】 The research of the methods of the determination of Pt in bio-samples of small white mouse has done by GFAAS.With combination of two-steps ashes and Zeeman background corrections,the background interference of bio-samples has been overcome and a simple method of determination of Pt in bio-samples has been set up.The RSD of urine was 3.00%t、he RSD of the dissolved solution of kidney was 5.26% and the RSD of the serum was 9.42%.更多还原
