高放废液中的硝酸根、硫酸根含量约为40、4g/L。分析硝酸根时,需把样品稀释10000倍,分析硫酸根时,需把样品稀释1000倍,以使样品中的硝酸根、硫酸根浓度为几mg/L。使用EP-2000离子色谱仪(北京历元电子仪器技贸公司产),按如下色谱条件进样分析:淋洗液(1.8mmol/L碳酸氢钠-1.7mmol/
High-level liquid waste nitrate, sulfate content of about 40,4 g / L. When analyzing nitrate, you need to dilute the sample 10000 times. When analyzing sulfate, you need to dilute the sample 1000 times so that the concentration of nitrate and sulfate in the sample is a few mg / L. Using EP-2000 ion chromatography (Beijing calendar yuan electronic technology and trade company), according to the following chromatographic conditions, injection analysis: eluent (1.8mmol / L sodium bicarbonate -1.7mmol /
