离子色谱法测定水稻秸秆降解液中的氟离子和氯离子OACSTPCD
Determination of fluoride and chloride anions in rice straw degradation solution by ion chromatography
建立了一种使用碳酸盐淋洗联合离子色谱法测定水稻秸秆降解液中氟离子和氯离子的方法.用涡旋仪振荡混匀样品后立即吸取50 mL样品,C18固相萃取小柱真空抽滤,用超纯水稀释1 000倍后测定秸秆降解液中氟离子和氯离子.结果表明:水稻秸秆降解液中氟离子和氯离子互不干扰,分离度较好.氟离子线性范围为0.1-2.0 mg/L,线性相关系数为0.9960;氯离子线性范围为2.0-40.0 mg/L,线性相关系数为在0.9981.用该方法测定两种离子相应浓度的标…查看全部>>
A method for the determination of fluoride and chloride in rice straw degradation solution by carbonate leaching combined with ion chromatography was established.The sample treatment method was as follows:after shaking and mixing the sample with a vortex instrument,immediately sucked 50 mL of sample,vacuum filtered with C18 solid-phase extraction column,diluted 1 000 times with ultra-pure water,and then determined the fluoride ion and chloride ion in t…查看全部>>
