“…This means there is a high production of cassava peel (CP) agro‐waste resulting from CP that requires management as a solid waste. However, several studies have reported on the potential of CP for the reduction of heavy metals and organic matter from water and wastewater (Afolalu et al, 2022; Jain & Payal, 2021; Kumar et al, 2021; Schwantes et al, 2022). Nevertheless, none has reported the capacity of the CP as a biosorbent for the simultaneous remediation of Cl − and TH from contaminated groundwater.…”

In this study, activated carbon produced from cassava peel (CP) via carbonization at 400°C was utilized as a biosorbent for the removal of chloride (Cl−) and total hardness (TH) from groundwater. A response surface methodology (RSM) employing a Box–Behnken design (BBD) was implemented to optimize process parameters, including pH (3–10), biosorbent dosage (1–10 g), contact time (10–60 min), initial Cl− concentration (50–2000 mg/L), and initial TH concentration (40–900 mg/L). The biosorbent was applied in a batch reactor setup to evaluate its performance in removing Cl− and TH from groundwater under the optimized conditions. The experimental data showed good agreement with the model predictions, exhibiting R2 of 0.991 and 0.905 for Cl− and TH removal, respectively. The CP biosorbent removed Cl− (245 mg/L) and TH (321 mg/L) by 84% and 90%, respectively, under optimal conditions of 6.9 g CP dose, 19.6 min, and initial pH of 8.1. The sorption kinetics followed a pseudo‐second‐order, and the equilibrium data fit the Freundlich and Langmuir models to Cl− and TH, respectively. The removal of Cl− and TH exhibited maximum adsorption capacities (qm) of 31.25 and 6.57 mg/g for Cl− and TH, respectively. Overall, CP shows potential as an adsorbent for remediating groundwater containing Cl− and TH.

The social progress, economic growth, and meteoric urbanization prompt the exploitation of available resources triggering the contagion of the biological and physical elements of the atmosphere irrationally causing global environmental pollution. Environmental contamination monitoring is a dire necessity. Although a number of technologies find mention in the literature for environmental remediation, however, environmental catalysis is an advanced steadily growing technique for pollution abatement. In this dimension, ceramic materials have turned heads due to their wide‐scale application areas. Hitherto, research is being done on advanced ceramics to fabricate novel modules for energy storage applications, in designing green buildings, pollution rheostats, and environmental engineering. This article deals with the abatement of environmental contaminants by adopting various methodologies such as aerobic and anaerobic biological treatments, adsorption, chemical oxidation, membrane separation, photocatalysis, ozonation using the ceramic as precursor materials. The ceramic membranes are cost‐effective, ecofriendly, efficacious, and green approach to obliterate toxins and harmful gases released in environment. Even though, limited literature is available on the abolition of harmful contaminants from air and soil using ceramic materials, an attempt has been made to present currently available data with best of our knowledge. This article will sensitize researchers to refabricate novel materials for environment sustainability.
