Turbidimetric Determination of Anionic Polyacrylamide in ...
reaction, PAM calibration curves (plots of PAM concentration vs. turbidity) were constructed individually as a factorial combination of three anionic PAMs, five solution compositions (DI water and four soil extracts), and seven concentration levels (0.5, 1, 2.5, 5, 10, 25, and 50 mg L-1). All combinations were
