Determination of anion content in PVC production water by ion chromatography
The ion chromatography method was used to determine the anion content in PVC pro-duction water.The content of common anions in PVC production wastewater and circulating water was determined using this method too.The results indicated that ion chromatography could accurately deter-mine the content of Cl-,NO3-and SO42-in water,but PO43-could not be detected due to its low con-tent.
