In this study, 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) and allylamine (AA) were copolymerized in an aqueous solution via free radical polymerization using ammonium persulfate as the initiator. The chemical structure and compositions of the copolymers were confirmed by elemental analysis, Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (NMR). Monomer reactivity ratios were determined by Fineman-Ross (rAMPS = 0.91 ± 0,01 and rAA = 0.40 ± 0.02), Kelen-Tudos (rAMPS = 1.10 ± 0.02 and rAA = 0.45 ± 0.01) and inverted Fineman-Ross (rAMPS = 0.85 ± 0.01 and rAA = 0.31 ± 0.03) methods. AMPS was found to be more reactive than AA and copolymers had a random composition. The flocculation performance of the copolymer was evaluated in Fe(OH)3 hydrosol. When the concentration of the copolymer in the hydrosol was more than 15 mg/L, the concentration of Fe3+ ions decreased up to 15 times due to flocculation of hydrosol particles. Effect of the concentration of AMPS-AA copolymer on the electropotential (zeta) and particle size of the hydrosol Fe(OH)3 were also studied systematically. It was determined that the zeta potential of the particles decreased from + 58 to + 20 mV and the average particle size of the hydrosol increased approximately 30 times when copolymer concentration in the hydrosol reached to 20 mg/L. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.DOI
