【摘要】 采用沉淀、络合滴定法,间接快速地测定了重晶石中钡的含量。对重晶石熔样方式、络合反应条件及共存干扰离子的消除方法进行了研究。该方法快速、准确,回收率为98.5％～100.7％,RSD小于2.48％。更多还原

【Abstract】 The melting sample, their complex action condition and elimination of coexisting interfering ions of barite were studied and barium in the barite was fast and indirectly determined by precipitation and complexometry. The method is fast with precise result, and the recovery is 98. 5% - 100. 7% and RSD is < 2.48% .更多还原
