Removal of lead ions in aqueous solution by hydroxyapatite/polyurethane composite foams

We have prepared hydroxyapatite/polyurehthane (HAp/PU) composite foams with two different HAp contents of 20 and 50 wt.% and investigated their removal capability of Pb 2+ ions from aqueous solutions with various initial Pb 2+ ion concentrations and pH values of 2–6. HAp/PU composite foams synthesiz...
