BACKGROUNDThe removal of lead ions (Pb2+) from industrial wastewater can be achieved using adsorption technology. Composites of zeolitic imidazolate framework‐8 (ZIF‐8) and graphene oxide (GO) were prepared via room temperature synthesis (RTS) using RO water as the solvent and by mixing GO with separated parts of ZIF‐8 precursors before its combination. Three weight percentages of GO, 10wt%, 30wt% and 50wt%, were used to synthesize ZGH10, ZGH30 and ZGH50 to determine optimum preparation and application conditions.ResultsZGH30 showed the most outstanding performance as an adsorbent for Pb2+ removal from aqueous solution. As captured by field emission scanning electron microscopy image, ZGH30 showed an adequate amount of ZIF‐8 grown on all surfaces of thr GO sheet, with an appropriate exposure of GO sheet layers for further Pb2+ interaction. The Pb2+ adsorption test revealed that ZGH30 obtained the optimum operating values between pH 5 and 6, using 10 mg dosage and it could remove ≤97% of 100 mg L−1 Pb2+. Additionally, ZGH30 achieved the most rapid equilibrium time within 10 min, similar to ZGH50, as compared to their individual components, ZIF‐8 (240 min) and GO (300 min). The mechanism of Pb2+ adsorption fitted well with a Langmuir isotherm and pseudo‐second‐order kinetic model. The theoretical maximum adsorption capacities obtained through Langmuir isotherm were 200, 454.55, 476.19, 555.56 and 454.55 mg g−1, for GO, ZH, ZGH10, ZGH30 and ZGH50, respectively.ConclusionsTherefore, ZGH30 hybrid successfully unleashed its potential as the adsorbent for wastewater treatment technology with improved performance after modification. © 2023 Society of Chemical Industry (SCI).

Graphene is an excellent nanoscale allotrope of carbon in which carbon atoms are bonded through sp2 hybridization. Graphene itself or its thin film exhibits excellent transparency to visible light. Silver nanowires are also being used for making transparent electrodes. Herein, we prepared a thin film of reduced graphene oxide and silver nanowires on flexible PET (polyethylene terephthalate) substrate. Characterization of graphene oxide/reduced graphene oxide has been carried out through X-ray diffractometry, FTIR (Fourier transformed infrared spectroscopy). Ultraviolet-visible spectroscopy and I-V measurements demonstrated high conductivity and transmittance of the above prepared film.
