| Abstract: | 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%. |
