Abstract

Pectin or modified pectin is used to remove the heavy metal ions in aqueous solution. The adsorption ability of pectin microspheres (PMs) and pectic acid microspheres (PAMs) for Pb (II) in aqueous solution were characterized by the parameters such as pH, initial concentration, and contact time for Pb (II) removal in this work. The results showed that adsorption for 150 min at pH 5 was the optimal condition. The maximum adsorption capacity of PMs and PAMs for Pb (II) was 127 mg·g-1 and 325 mg·g-1, respectively. Five-cycle reusability tests demonstrated microspheres could be repeatedly used. All the results confirmed that PAMs which presented outstanding adsorption capability and reusability could be a good candidate for wastewater purification.
