在用离子色谱法测定温泉水样中F~-、Cl~-、Br~-、NO_2~-、NO_3~-、SO_4~(2-)、PO_4~(2-)等阴离子和Li~+、Na~+、K~+、Mg~(2+)、Ca~(2+)等阳离子过程中,研究了用油泵超声波池内脱气法处理H_2CO_3过饱和水样以排除HCO_3~-对阴离子检测干扰的方法.研究采用青岛普仁仪器有限公司生产的PIC-8型离子色谱仪,分离柱为TSK-GEL SuperIC-CationColumn(150 mm×4.5 mm)离子分离柱,以1.9 mmol/L碳酸钠-1.8mmol/L碳酸氢钠作为阴离子淋洗液,流量为1.5 Ml/min;以2 mmol/L HNO_3为阳离子淋洗液,流量为1.0 ml/min,测定了腾冲火山区叠水河、大滚锅两个温泉水中的阴阳离子的含量.研究结果表明:该方法简便、快速、准确可靠,可在火山和地震监测中推广使用.

Determination of inorganic anion and cation in hot spring water sample are widely used in the volcano and earthquake monitoring.To eliminate interference of HCO_3~- on the anion detection by using ultrasonic pump ikeuchi degassing treatment H_2CO_3 supersaturation water samples,the anions(F~-、Cl~-、Br~-、NO_2~-、NO_3~-、SO_4~(2-)、PO_4~(2-)) and cations(Li~+、Na~+、K~+、Mg~(2+)、Ca~(2+))in the hot spring were determinated by Ion Chromatography.The content of ions in two hot spring water samples,Dieshui river and Dagunguo in Tengchong volcano area,was detected by the PIC-8 ion chromatograph with TSK-GEL ions separation column (150 mm×4.5 mm).The mixed solution of 1.9mmol/L Na_2CO_3-1.8mmol/L NaHCO_3 was using as anion flow-phase system at a flow rate of 1.5 ml/min,and as cation flow-phase system,the solution of 2 mmol/L HNO_3 was using at a flow rate of 1.0 ml/min.The method was proved to be accurate,convenient and rapid,could be widely used in the volcano and earthquake monitoring.
