Abstract EN
To improve the adsorption performance and regeneration ability of adsorbent, a simple method was designed to synthesize long TiO2 nanotube/reduced graphene oxide (rGO-TON) hydrogel, which has good adsorption and regeneration capacity toward ciprofloxacin.
rGO-TON hydrogel could form 3D structure, which makes the separation and regeneration of adsorbent easy.
For comparison, commercial P25 particle is used to prepare composite hydrogel with rGO; the results showed that TiO2 nanotube supports the graphene sheets better than P25 particles, which would reduce the agglomeration of graphene sheets.
rGO-TON have larger specific surface area (138.2 m2/g) than rGO-P25 (79.4 m2/g).
In this paper, ciprofloxacin was chosen as target pollutants, the rGO-TON obtain excellent adsorption capacity, and the maximum adsorption capacities of rGO-TON for ciprofloxacin calculated from Langmuir model are 178.6 mg/g (R2=0.9929), 181.8 mg/g (R2=0.9954), and 108.7 mg/g (R2=0.9964) for graphene oxide (GO), GO-TON, and GO-P25, respectively.
In regeneration, the adsorption capacity of rGO-TON and rGO-P25 has little reduced after 5 cycles, while the adsorption capacity of rGO decreases to below 100 mg/g.
Results of this work are of great significance for environmental applications of regenerable long TiO2 nanotube/graphene oxide hydrogel as a promising adsorbent nanomaterial for antibiotic pollutants from aqueous solutions.
