摘要
氟、磷酸根和六氟磷酸根离子在流速为 0 .2 5ml·min- 1,淋洗液为 0 .0 0 1mol·L- 1Na2 CO3和 0 .0 0 5mol·L- 1NaOH溶液 ,在离子色谱仪上能较好地分离。氟、磷酸根和六氟磷酸根离子的检出限分别为 7.2 9,70 .5和 2 95ng·ml- 1,该方法具有良好的线性 ,测定结果有较好的重现性。
It is reported that fluoride, phosphate and hexafluorophosphate ions were successfully separated by ion chromatography using a mixed eluent composed of 0.001mol·L -1 Na 2CO 3 and 0.005mol·L -1 NaOH at a flow rate of 0.25ml·min -1 . The detection limits ( S/N =3) found are 7.29, 70.5 and 295ng·ml -1 for fluoride, phosphate and hexafluorophosphate ions respectively. Good linearity and repeatability are proved by experimental results. The above mentioned method has been satisfactorily applied to the analysis of lithium hexafluorophate.
