Abstract: Ion-imprinting technique based on microalgae biomass surface was applied to the preparation of surface ionic-imprinted biosorbent (SIIB) for Cu(II) adsorption. The biosorbent was prepared by coating Cu(II)-imprinted chitosan hydrogel onto biomass surface followed by cross-linking procedure. Desorption of the imprinted-ions left a specific template for Cu(II) binding sites. Batch adsorption was conducted to study the characteristics adsorption of Cu(II) onto SIIB, and the maximum capacity was calculated to be 53.1918 mg/g, higher than that on IIB (51.5469 mg/g). Desorption metal ion-imprinted on SIIB was more effective (96-100%) than that on IIB (60-70%), which offers promising applicative prospects in the wastewater treatment
