| 摘 要： | 土壤样品经超声波超声静置,提取上清液,经渗析进入色谱柱,采用Metrohm A Supp 4-250阴离子交换柱,以1.8 mmol/L碳酸钠-1.7 mmol/L碳酸氢钠混合溶液作为流动相,用在线渗析技术与离子色谱法联用测定土壤中的有效氟。与常规方法相比,建立的方法操作简单,避免了繁琐的样品前处理。加标回收率为90.5%～95.7%,精密度(RSD,n=6)为1.60%。该方法具有高效、快速、灵敏等特点,能够用于环境土壤样品中有效氟的检测。

| Abstract: | A method of on-line dialysis with ion chromatography was used to quantify levels of available fluorine in topsoil samples.The topsoil samples were extracted by ultrasonic wave.The upper clear solution was on-line treated with dialysis and then separated with the Metrosep A Supp 4-250 Anion Exchanger Column.A mixed solution of 1.8 mmol/L Na2CO3 and 1.7 mmol/L Na2HCO3 was used as the mobile phase.Comparing with the routine analysis method,this new method is simple and avoids complicated pretreatment of the sa... |
