^aQ_e and Q_t are the amount of dye adsorbed per gram of MIL-100(Fe)@PAN (mg g^–1) at equilibrium and time t, respectively. k₁ and k₂ are the pseudo-first-order (min^–1) and pseudo-second-order (g mg^–1 min^–1) rate constants, respectively. C_e is the equilibrium dye concentration in solution (mg L^–1). In the Freundlich isotherm model, k_F and n are obtained from fitting the experimental results to the model.
