Comparision Between HPLC and Starch-cadmium Iodine on Determining the Cocentration of Polyacrylamide

This research examined the method of polyacrylamide concentration determined by HPLC. The influence of polyacrylamide molecular mass on the measuring accuracy was discussed. Compared to classic starch-cadmium iodine，polyacrylamide concentration determined by HPLC method is accurate for well produced fluid which has much more interference factors. HPLC method is valuable for the determination of polyacrylamide in other solvents.
