(a) Adsorption kinetics of M-PMs and PMs for MG (test conditions: at 35 °C, pH 7, initial MG concentration = 10 mg/L, dosage of polymer microspheres = 0.05 g, and volume of the MG solution = 250 mL). (b) Plot of lnK₀ as a function of 1/T (test conditions: pH 7, initial MG concentration = 10 mg/L, dosage of polymer microspheres = 0.01 g, and volume of the MG solution = 10 mL). (c) Isothermal adsorption patterns for the adsorption of MG by M-PMs, along with the Langmuir and Freundlich fittings (test conditions: pH 7, initial MG concentration = 3 mg/L, dosage of polymer microspheres = 0.01 g, and volume of the MG solution = 4 mL).
