a In situ FT-IR spectra of P-Lig upon UV irradiation for 0 s (black line), 150 s (red line) and 600 s (blue line); b Calculated interaction model between lignosulfonate and acrylamide with different polymerization degrees; c Lifetime of P-Lig prepared from ionic liquid with different anions (Error bars indicate the standard deviation for three separate measurements of the samples, the lifetime of the sample containing Br− is 109.72 ± 0.52 ms, the lifetime of the sample containing Cl− is 89.27 ± 0.43 ms, the lifetime of the sample containing CH3COO− is 38.67 ± 0.41 ms).
