摘要
建立了离子色谱法测定焦化废水中多种阴离子的方法。比较了液液萃取、真空抽滤、固相萃取3种处理方法。用电导检测器同时测定了焦化废水中的F-、Cl-、NO2-、NO3-、PO43-含量。离子色谱法的回收率为69%～110%,相对标准偏差为0.13%～3.6%。
The method for determination of many kinds of anions in coking waste water by ionic chromatography is established. The 3 kinds of treating methods of liquid-liquid extraction, vacuum pumping and filtering and solid phase extraction are compared. The contents of F-,Cl-,NO2-,NO3-,PO43- in coking waste water are determined by electric conductivity detector simultaneously. The recovery rates of ionic chromatography range from 69% to 110% and relative standard deviations are in the range from 0.13% to 3.6%.
