本文报导话检胃粘膜样品中痕量铜和锌的原子吸收法测定。采用了微痕量分析技术;用硝酸—过氧化氢硝解试样;石墨炉原子吸收法测定铜;火焰原子吸收法测定锌。样品的检出跟:铜1.7μg/g;锌8.0μg/g,回收率和精密度,可以满足微痕量分析的要求。本法快速简单,适用于人体组织活检样品中Zn/Cu值的测定,为临床诊断提供数据。 This article reports the determination of trace amounts of copper and zinc in gastric mucosa samples by hand by atomic absorption spectrometry. Micro-trace analysis techniques were used; samples were nitrolyzed with nitric acid-hydrogen peroxide; copper was determined by graphite furnace atomic absorption spectrometry; zinc was determined by flame atomic absorption spectrometry. The samples were detected with: copper 1.7μg / g; zinc 8.0μg / g, recovery and precision, to meet the trace trace analysis requirements. This method is fast and simple, suitable for the determination of Zn / Cu value in human tissue biopsy samples, providing data for clinical diagnosis.
