Simulated Oilfield Produced The Water Pam Detection And Degradation Studies

In this paper, starch cadmium iodide and turbidimetry were used to determine the concentration of polyacrylamide(PAM) which was the target object. The optimal test conditions of each method were determined. The precision and measurement range were analysed.The PAM solution was degradated by photocatalysis and electrocatalysis technology, the influencing factors and optimal conditions were investigated through single factor experiments. And the effect of total dissolved salt concentrations and different ions on PAM degradation was discussed. In oder to improve the degradation ratio, the ultrasound-electrocatalysis, photocatalysis-electrocatalysis and ultrasound-photocatalysis-electrocatalysis were studied.The degradation pathway was studied through viscosity,IR,HPLC。...
