Determination of trace anions in hydrogen peroxide by ion chromatography with preconcentration technique(预浓缩技术-离子色谱法测定过氧化氢中痕量阴离子)
建立了预浓缩-离子色谱法测定过氧化氢中痕量阴离子的方法。通过预浓缩技术去除过氧化氢基体,有效地消除了过氧化氢对分离树脂的氧化破坏作用.色谱条件是：Ion Pac AS23离子交换柱,等度淋洗,抑制型电导检测.该方法样品中阴离子F-, Cl-,NO3- ,SO42-检出限(S/N = 3)分别为3.0,5.0,8.0及9.0 μg •L-1.该方法具有灵敏度高、选择性好、操作简单、价格便宜等特点....
