固体直接进样原子吸收测定,是近十年迅速发展起来的一种较简便的方法,具有省时、不引入污染和取样量小的优点,但要求条件较为苛刻。本文意在通过测定花岗岩中的微量铷,探索适用常规条件固体直接进样测定的可能性。实验条件 (一)仪器与试剂 P-E703型原子吸收分光光度计,附HGA-500型石墨炉,AS-1自动取样器。 Direct solid-phase atomic absorption spectrometry is a relatively simple method developed rapidly in recent ten years. It has the advantages of saving time, not introducing pollution and small sample size, but the requirements are more demanding. This article is intended to explore the possibility of direct solid injections using conventional conditions by measuring trace rubidium in granite. Experimental conditions (a) instruments and reagents P-E703 atomic absorption spectrophotometer, with HGA-500 graphite furnace, AS-1 autosampler.
