【摘要】 选择Ｚｎ的非灵敏线，采用原子吸收分光光度法测定锌精矿中高含量锌。共存离子互不干扰，平均回收率为９９．８２％，对于锌精矿测定５次，其ＲＳＤ＜０．５％。该法所测结果与国家标准分析方法测定的结果相符，且较标准分析方法简便、快速，实用性强。更多还原

【Abstract】 A method for the determination of zinc in zinc concentrates by atomic absorption spectrophotometry with non sensitive line is reported in this paper. Co existent metallic ions do not interfere with determination of zinc. The method is simple, rapid and practical. The average recovery is 99.82% with precision of <0.5% RSD ( n =5). The method has been applied to the determination of zinc in zinc concentrates and the results are in good agreement with those provided by state standard method.更多还原
