利用通用的高压液相色谱仪和间接紫外检测法,在Vydac 302IC柱(φ0.46×25cm)上,流动相为7mmol/l邻苯二甲酸氢钾:4mmol/l邻苯二甲酸=80/20,(Ⅴ/Ⅴ),pH=3.9混合溶液,流量为2ml/min,紫外检测波长为300nm时,对高放废液玻璃固化过程尾气流出物中的无机阴离子NO_2~-,NO_3~-和SO_4~(2-)等进行了分析测定。分析时间不超过12min,测量精度为0.2-1.0％,最小检出量为10~(-7)-10~(-8)g。此方法不需抑制柱和专门的离子色谱仪,快速、简便、灵敏、重现性良好。 The mobile phase was 7 mmol / l potassium hydrogen phthalate: 4 mmol / l ortho-phthalic acid = 80 / 20, (Ⅴ / V) and pH = 3.9, the flow rate was 2ml / min and UV detection wavelength was 300nm. The results showed that the inorganic anions NO_2 ~ -, NO_3 ~ SO_4 ~ (2-) were analyzed and measured. Analysis time does not exceed 12min, measurement accuracy of 0.2-1.0%, the minimum detectable amount of 10 ~ (-7) -10 ~ (-8) g. This method does not need to inhibit the column and a special IC, fast, simple, sensitive, reproducible.
