本文介绍了用原子吸收光谱法测定人体组织和体液中铂的方法。无需预处理或稀释即可分析血清和尿液。比较了湿法灰化和干法灰化消化组织的方法。在炉中干燥灰化组织导致分析物的显著和无法解释的损失，而当组织湿灰化时，加入组织中的铂完全回收。湿法灰化技术快速方便，需要最少的样品处理。
Methods for determination of platinum in body tissues and fluids by electrothermal atomic absorption spectroscopy are described. Serum and urine could be analyzed without pretreatment or dilution. Wet and dry ashing techniques for tissue digestion were compared. Dry ashing tissues in a furnace resulted in significant and unexplained losses of analyte, whereas there was complete recovery of platinum added to the tissues when the tissues were wet ashed. The wet ashing technique is fast and convenient and requires minimal sample treatment.
