摘要
采用火焰原子吸收分光光度法对市售珍珠粉中部分金属元素进行了测定,然后将珠珍粉按粒度大小过筛,分别用蒸馏水与pH≈1.4的盐酸进行浸泡溶出,并对溶出液中七种元素进行了测定。结果表明,粒度与酸液对金属元素的溶出皆有影响,这对珍珠粉的正确使用有一定的指导意义,也为天然产物中金属元素的形态分析提供参考数据。
We have determined seven metallic elements in various extract of pearl powder by FAAS.The result implies that the quantity of different element in water and acidic solvent system is different.It has supplied reference data for the further studies of speciation of metallic elements in natural product also.
