Abstract

•PVA/GO-Glu hydrogel as microbial carrier was prepared by chemical crosslinking.•Much more PVA molecules were grafted onto GO surface in presence of glutamic acid.•Addition of GO-Glu improved the crosslinking density of the composite hydrogel.•Addition of GO-Glu led to improvement of SSA and biocompatibility of PVA hydrogel.•Adding GO-Glu improved microbial load capacity and COD removal rate of hydrogel.
