Abstract: The spherical macroporous cellulose (SMC) was fabricated using medical absorbent cotton as raw material and nano CaCO3 as porogenic agents. And then, the phenylglycine was grafted onto the SMC to obtain the novel spherical macroporous cellulose derivative adsorbent (PSMC). FT-IR and scanning electron microscope (SEM) were employed to characterize the adsorbents and Fe3+ ions served as model solute to evaluate the adsorption property of the adsorbents. The experimental results show that the amount of porogenic agents and the value of pH have obvious influence on adsorption capacity of the adsorbents. The data of adsorption kinetic and isotherm display that the adsorbents possess excellent equilibrium adsorption capacity (348.94 mg/g) and have a bright prospect and considerable potential in the treatment of Fe3+ ions in wastewater.
