The Hb adsorption properties of the as-prepared cellulose/HA nanocomposites (sample M70): (a) the amount of Hb adsorbed at equilibrium (q e ) as a function of initial concentrations (c i ) of Hb; (b) Hb adsorption percentage as a function of c i of Hb; the inset shows the exponential relationship of cellulose/HA nanocomposites between the amount of Hb adsorbed at q e and equilibrium concentrations (c e ) of Hb; (c) the amount of Hb adsorbed at q e as a function of sample mass; the inset is the optical photographs of the Hb solutions (3 mg mL−1) before and after absorbed by the cellulose/HA nanocomposites with different sample masses (0–40 mg); (d) Hb adsorption percentage as a function of sample mass.
