Spectrophotometric Determination of Polyacrylamide in Waters Containing

The DOM moiety, which is proportional to DOM concentration, was determined by spectrophotometry using a UV 254-nm wavelength. The actual PAM concentration of a water sample (soil extract containing PAM in this study) was obtained from NBM readings subtracted by the interferential DOM contribution using a correction curve.

Spectrophotometric determination of polyacrylamide in waters containing

Using polyacrylamide (PAM) to reduce soil erosion in irrigated land has increased rapidly in recent years. A simple and reliable method to measure the PAM concentration in waters containing dissolved organic matter (DOM) is of great importance in assessing the fate and efficiency of PAM application.

Spectrophotometric Determination of Substrate-Borne Polyacrylamide

The N-bromination method (a PAM analytical technique based on N-bromination of amide groups and spectrophotometric determination of the formed starch?triiodide complex), which was originally developed for determining PAM in aqueous solutions, was modified to quantify substrate-borne PAM.

Spectrophotometric Determination of Polyacrylamide in Aqueous Solutions

Spectrophotometry was used to study the interaction of high-molecular polyacrylamide with cationic dyes: Methylene Blue, Acridine Yellow, and Toluidine Blue. Polyacrylamide samples were modified by alkaline hydrolysis. The optimum conditions of the formation of polyacrylamide¨Ccationic dye adducts and their compositions were found.

Determination of polyacrylamide in soil waters by size exclusion

Polyacrylamide was separated from interferential salts and DOM on a polymeric gel column eluted with an aqueous solution of 0.05 M KH2PO4 and then detected at a short UV wavelength of 195 nm. Analysis of PAM concentrations in soil sorption supernatants, soil leachates, and water samples from irrigation furrow streams showed that SEC is an
