    2020-5-11 · The 1 H NMR spectra were measured on Bruker AV400 NMR spectrometer, and tetramethylsilane (TMS) was used as the internal standard. The FTIR spectra were recorded on Thermo Nicolet‐IS10 FTIR spectrometer. The thermal gravimetric analysis (TGA) was performed on a NETZSCH TG 209 F1 instrument under nitrogen atmosphere at the heating rate of 10°C/min from 30°C to 600°C.

    2016-1-4 · The vast majority of commercial flocculants are based on partially hydrolyzed polyacrylamide. As a result of hydrolysis even nonionic polyacrylamides contain some anionic groups. This is expressed as degree of anionicity (the degree of anionicity of completely hydrolyzed polyacrylamide is 100%, so it is a polyacrylic acid).
