【摘要】 研究了固体粉末悬浮液的进样方法，采用将悬浮液经超声波发生器对固体微粒进行分散后，在磁搅拌下，以动态方式引入ＩＣＰ测定。进行了悬浮液浓度、溶液酸度、进样量等因素对测定的影响试验，回收率结果表明，该进样方法简便，重视性好，是一种可行的进样方法更多还原

【Abstract】 Sample suspension prepared by ultrasonic dispersion and stabilized with magnetic stirring is injected into the ICP sample system. A seriers tests on concentration, time, pH value, precision and recovery were made. The sresults showed that this sampling method is convinient and with high reproducibity and it’s a practicable method.更多还原
