(a) Phosphate adsorption kinetics data plot for raw HNT and 1Fe-HNT and adsorption within first 30 min (inset). Modeling of phosphate adsorption kinetics with (b) pseudo-second order and (c) intraparticle diffusion models. Initial phosphate concentration: 10 mg L−1, pH 5.0, sorbent dosage 3 g L−1, shaking speed 240 rpm.
