Linear description of CHL adsorption onto PGA-co-PDL NPs. Ce is the residual CHL concentrations in the suspension at equilibrium (mg/mL) and q is the amount of adsorbed CHL per unit weight of NPs. All models (A) Langmuir, (B) BET, (C) Freundlich (D) Halsey were fit utilizing concentrations of 2–20 mg/mL; however, the Langmuir model was also fit to low concentrations (0–8 mg/mL) (black) (n = 3).
