Abstract

A rapid and sensitive method of the assay of polyacrylamide in drilling fluids at the drill site for oil exploration is described. Base hydrolysis and a gas sensing electrode are utilized. Polyacrylamide was determined from 0.031 to 4.81 w/w% with an average error of 1.79% and an average standard deviation of 0.17.
