| 摘 要： | 以氢氧化钾为流动相,阴离子交换分离,抑制电导检测,可以同时分离F-、Cl-、Br-、NO3-、SO42-、PO43-I、-等海水中的常见阴离子,利用梯度淋洗可以使以上各种离子在其最佳保留时间和最佳峰形条件下出峰。以8 mmol/L H2SO4为淋洗液,阳离子交换分离,抑制电导检测,可以同时分离测定海水中的Na 、K 、Mg2 、Ca2 、Sr2 和Ba2 。在所采用的色谱条件下各阴阳离子均可以得到很好的线性和很低的检出限。 |

| Abstract: | Using self-generating KOH as eluent,several routine ions in the sea water,such as F~(-),Cl~(-),Br~(-),NO~-_(3),SO~(2-)_(4),PO~(3-)_(4) and I~(-) can be determined simultaneously with anion-exchange,gradient separation,and suppressor conductivity detection.Using 8 mmol/L H_2SO_4 as eluent,Na~( ),K~( ),Mg~(2 ),Ca~(2 ),Sr~(2 ) and Ba~(2 ) in the sea water can be determined simultaneously with cation-exchange separation and suppressor conductivity detection.Each cation and anion can get favorable linearality and low detection limit. |
| Keywords: | Ion chromatography Suppressor conductivity detection Seawater |
