微波消化骨中钙、镁、磷、钾、钠、铁、锌和氟的测定

Determination of Ca,Mg,K,P,Na,Zn,Fe and F in Bone with Microwave Digest

目前 ,微波消化技术广泛应用于分析化学领域 ,该技术与传统的样品消解方法 (干法灰化、湿法消化 )比较 ,具有简单、快速、省试剂、污染少、消化完全等优点。用原子吸收光谱法测定了骨中钙、镁、磷、钾、钠、铁、锌和氟等元素 ,除了氟、磷元素以外 ,加标回收率为 6 6 40 %～ 110 91% ,变异系数 (CV)为 10 %以内 (0 32 %～ 7 6 1% )

Microwave digest technique is widely applied in the analytical chemistry field. Comparing with traditional sample digestion method, i.e. wet digest or dry digest. microwave technique is simple, rapid, little contaminative and saves reagent, digests completely. Elements in the bone such as Ca, Mg, P, K, Na, Fe, Zn and F are determined by atomic absorption spectrometry. Their recovery ratio is 66.4%-110.9%, variation coefficient is 0.32%-7.61% except fluorine and phosphor.
