In this contemporary era, chitosan has gained exceptional attention as a sustainable biopolymer in the adsorption process due to its nontoxic nature, biocompatibility, accessibility, and pH-responsive active surface charge. This study developed a high-performance chitosan/poly(vinyl alcohol) adsorbent through metformin functionalization. The incorporation of poly(vinyl alcohol) (PVA), along with the metformin-activated surface, remarkably ameliorated its physiochemical properties. The abundance of inter-and intrahydrogen and chemical bonds in the porous structure enhances the specific surface area up to 83.8 m 2 /g. Series characterization methods are utilized to investigate the adsorbents' characteristics in all aspects and the removal performance. Furthermore, the key factors for the adsorption process, including the influence of pH, adsorbent quantity, time intervals, and preliminary concentration, were studied and optimized. The optimal pH was observed in the neutral moiety, which is crucial from an industrial perspective. Due to the presence of countless nitrogen and oxygen atom-containing backbones, the CS/ PVA-Pr-Met biocomposite has demonstrated considerable adsorption capacity toward Pb(II) ions and levofloxacin with the highest adsorption capacities of 313.162 mg/g for Pb(II) and 2872.927 mg/g for levofloxacin concerning their molecular and ionic nature and various adsorption mechanisms. In accordance with the correlation coefficient and estimated parameters, the adsorption of Pb(II) and levofloxacin onto the beads mostly follows the pseudo-second-order kinetics (R 2 ≥ 0.997) and the Langmuir adsorption isotherm model (R 2 ≥ 0.995). The exceptional adsorption capacity coupled with the porous structure of the modified hydrogel beads has promising applications for efficient wastewater treatment

Hexavalent chromium (Cr(VI)) exists in water as carcinogenic anionic species. Here, waste cotton fabric (WCF) was recycled and given a second life as a support for Cr(VI) colorimetric detection. WCF was prepared by grafting 2,3-epoxypropyltrimethylammonium chloride on its surface to make it cationic (cWCF) and suitable for Cr anion adsorption via electrostatic interactions. Two strategies were assessed for Cr(VI) detection in water. In the first method, cWCF was functionalized with color-developing 1,5-diphenylcarbazide (DPC), and the resulting strip was evaluated for Cr(VI) quantification. This sensor exhibited a short response time of 30 s with a limit of detection (LOD) of 0.029 mg/L. In the second method, Cr(VI)-containing samples were initially preconcentrated by adsorption on the cWCF substrate, and then, DPC was added for color development. With this system, the LOD was excellent at 0.0013 mg/L, but the response time was longer at 5 min. Another advantage of the robust cWCF support is that it could be washed and reused multiple times for Cr(VI) detection. The two approaches described here are inexpensive and can be selected for different purposes depending on the sensitivity required as well as the volume of samples and time available to complete the Cr ion assay.

“…The treatment of wastewater involved with heavy metal ions has been explored in the past using various nanomaterials such as carbon nanotubes, metal oxides, and magnetic, polymer-based, carbonaceous materials and zeolites. By adsorbing the heavy metals on their surfaces, these nanomaterials primarily remove the metal ions. − The nanomaterials also showed dual applications such as detection and sorption capability . Silica-based mesoporous materials have recently been functionalized with different ligands to allow optimal monitoring and recovery of various metal ions .…”

Heavy metal pollution results in enormous environmental impacts and significant human health problems. Because of their extreme toxicity and lack of biodegradability, heavy metal ions in water are considered problematic. Although the removal of various heavy metal ions from wastewater has been widely investigated, heavy metal contamination still requires effective and suitable remediation. With special attention on heavy metal removal, this study reviews recent advances, breakthroughs, and potential applications of various physical, chemical, and biological methods. Each treatment method has specific mechanisms of interaction with metal ions, which are described in this review. The discussion in this review leads to the conclusion that adsorption has the best potential which leads to the sustainable remediation of heavy metals. In summary, the review provides a new perspective on heavy metal reduction and encourages the development of innovative strategies for heavy metal removal. The main current problems and prospects in this field are highlighted in this review.
