A method for measuring the degree of anionicity of polyacrylamide-based

Abstract A simple procedure was described for routine measurements of the degree of anionicity of polyacrylamide-based flocculants. The method relies on determining the total organic carbon content and assaying ion concentrations in a dilute solution (in distilled water at natural pH) of the tested flocculant.

The sample is a high-molecular-weight (18 million Dalton), linear, anionic polyacrylamides containing 72.2 mol% of acrylamide and 27.8 mol% of acrylate. Brine. A solution of potassium chloride (KCl) and 400 ppm sodium azide (NaN 3) in tap water was used as make-up brine. NaN 3 is used as a bactericide.

Synthesis and Characterization of Acrylamide-Based Anionic ... - Hindawi

The copolymer of acrylamide (AM) and 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) was synthesized through radical solution polymerization by potassium persulfate as initiator. By changing the AMPS feed ratio from 10 to 70%, and keeping other reaction conditions constant, different copolymers were synthesized. The techniques of Fourier transform infrared (FTIR) and nuclear magnetic

The commonly reported polyacrylamide FTIR reveals a broad band at approximately 3300 cm ?1 and a characteristic peak at 3191 cm ?1, which infers the stretching vibration of N¨CH . However, in this study, the additional significant peak at 1417.36 cm ?1 of ¨CCH2 groups on the chains confirms the successful copolymerization.
