title: [Determination of Ca, Mg, K, P, Na, Zn, Fe and F in bone with microwave digest].
abstract: 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.
