摘要
介绍了离子色谱法测定城市生活垃圾渗沥水中的阴离子(氯离子、亚硝酸根离子、硝酸根离子、磷酸根离子和硫酸根离子).避免了样品中复杂组分对分析体系的干扰及对色谱系统的污染,该方法快速、灵敏、准确.当以10mmol/LNa2CO3作淋洗液,流速为1.0mL/min时,分离效果良好,阴离子的检出限分别为0.18,0.45,0.67,1.02和0.85mg/L,回收率为95.85%～106.5%.
This paper introduces a technique for determining of anions in leaching solution of municipal solid wastes by using ion chromatography. Disturbing system analysis of complicated composition was avoided. Results show that the determining method is simpler,quicker,and more accurate. The limits of detection for Cl-、NO2-、NO3-、PO43-and SO42-were 0. 18,0. 45,0. 67,1. 02 and 0. 85 mg/L,respectively. In addition, the recoveries were between 95. 85% and 106. 5% . The optimum condition is 10 mmol/L of Na2CO3in fluent at a flow rate of 1. 0 mL/min.
