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.
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 0.28μg/g.
