文摘

Effect of biofilms on the transport of GONPs was systematically examined. XMCT was used to quantitatively characterize the pore structures of packed columns. Biofilms reduced the porosity and narrowed the pore sizes of sand columns. The presence of biofilms provides favorable sites for GONPs retention/attachment.
