【摘要】 样品用碳酸钠和氧化锌混合熔剂半熔,用80℃~100℃水提取,用强酸型阳离子树脂分离溶液中的大量钠等阳离子,采用电感耦合等离子质谱直接测定溶液中的溴和碘。测定下限溴为0.15μg/g,碘为0.028μg/g。更多还原

【Abstract】 Using semi-melting method-mixed semi-melting sodium-bicarbonate and zinc oxide,extracting water of 80℃~100℃,using strong acid action exchange resin to separate a large number Na from solution,using inductive coupling plasma mass spectrometry to datermine Br and I directly in solution.The Br of the lower limit is 0.15μg/g,and I is 0.028μg/g.更多还原
