Abstract
⺠The morphology, content and distribution of ZrO2 nanoparticles inside the pores of GAC are affected by the type of GAC. ⺠Lignite ZrO2-GAC exhibited Zr content of 12%, while bituminous based ZrO2-GAC exhibited Zr content of 9.5%. ⺠The max. adsorption capacities under equilibrium conditions in 5 mM NaHCO3 buffered water matrix were â¼8.6 As/g Zr and â¼12.2 mg As/g Zr at pH = 7.6. ⺠The max. adsorption capacities under equilibrium conditions in NSF 53 Challenge water matrix while â¼1.5 mg As/g Zr and â¼3.2 mg As/g Zr at pH = 7.6. ⺠Introduction of nanoparticles did not impact the MB adsorption capacity of the lignite ZrO2-GAC, while the one of bituminous ZrO2-GAC decreased.
