Abstract

In the present study, a holey graphene oxide (HGO) was synthesized via fast-designed method for preparing HGO. The synthesized adsorbents were characterized by Fourier transform infrared spectroscopy. A simple adsorption method was designed for the removal of La (III) and Ni (II) by the utilization of HGO. The adsorption rate of La3+ progressively reached its maximum at 5 min and high adsorption Ni was achieved after 90 min. Langmuir isotherm for the adsorption of La3+ and Ni2+ with a correlation coefficient (R2 = 0.9985, 0.9986), the adsorption is considered to be favorable 0˂ RL˂1. Freundlich model, with R2 = 0.99, 0.989. The adsorption is n = 2 ـ 10 so this is good adsorption. The experimental data is fitted , which confirms the obtained result from the Freundlich isotherm model. The pseudo-first-order model R2 was 0.96 and 0.99, respectively. The pseudo-second order model R2 was 0.98, 0.94, respectively. Moreover, the adsorption process takes place on heterogeneous surface adsorbent that is consistent with HGO nature. This model assumes that adsorption sites increase exponentially with adsorption, representing multilayer adsorption. Further La3+ could be adsorbed from a binary mixture (Ni-metal) that confirmed the feasibility and recovery increase for La3+ from Abs battery waste
