“…In recent years, Oxalate-based adsorbents have been applied to treat a wide variety of waterborne contaminants. They are immensely beneficial due to their biodegradability, costeffectiveness, non-toxicity, and global availability [31]. These adsorbents are extensively employed for the treatment of various metal ions, including nickel, cobalt, lead, and zinc, from aqueous environments and industrial effluents [32].…”

Ground granulated blast furnace slag (GGBS) is a primary industrial waste product of iron production, and its improper disposal has been a serious environmental problem. This study aims to modify the GGBS using oxalic acid (GGBS-Ox) for the adsorption of tetracycline (TC) from an aqueous solution. GGBS-Ox was synthesized and characterized via FTIR, XRD SEM, XPS, BET, and DLS. The effects of process parameters, involving initial solution pH, stirring speed, and contact time, are evaluated by utilizing response surface methodology (RSM), artificial neural network (ANN), and random forest (RF) based models. The experimental results indicate that the removal efficiency of TC is significantly affected by the initial pH of the solution. The RSM, ANN, and RF models accurately simulated the experimental data, as indicated by the high coefficient of determination (R2), which was 0.98, 0.95, and 0.98, respectively. Additionally, kinetics, isotherm, and thermodynamic models were evaluated for the adsorption of TC onto GGBS-Ox. The findings of this study demonstrated the utilization of GGBS-Ox as an efficient and sustainable adsorbent for the treatment of TC and can be considered as a potential adsorbent for wastewater treatment.

Mesoporous maltose/calcium oxalate hybrid material with abundant reaction sites and its efficient Pb(ii) removal from diverse water bodies

Abstract: Pb(II) shows severe toxicity even at trace levels due to non-biodegradability and biomagnification. At present, high capacity and selectivity as well as stability of adsorbents are still the main indexes...
