Waterborne heavy metals pose significant threats to both the environment and public health, causing neurological damage, developmental disorders, organ cancer. It is essential address contamination of various water bodies by these hazardous substances due their persistent nature lack biodegradability. This review thoroughly explores traditional modern strategies utilized remedy sources contaminated with evaluates effectiveness potential scalability each method. A literature survey reveals several effective for removing from water: adsorption, flotation, ion exchange, chemical precipitation, membrane-based filtration, coagulation, flocculation, phytoremediation, electrochemical methods. In our examination, we discussed agents/adsorbents used, efficiency removal technique, operating conditions, intrinsic advantages disadvantages approach. Summarizing key findings, noted a focus on adsorption techniques; however, challenges include selectively diverse ions, prolonged retention times, cycling stability. While membrane methods are practical, issues like large-volume sludge formation exist. Although electrical-based appear promising, solutions needed industrial-scale separation as well. Prioritizing real wastewater samples in studies crucial. Future research should emphasize eco-friendly, cost-effective

Nanoscience and nanotechnology for water remediation: an earnest hope toward sustainability

Nanoscale Horizons, Год журнала: 2024, Номер 9(6), С. 885 - 899

Опубликована: Янв. 1, 2024

Water pollution and the global freshwater crisis are most alarming concerns of 21st century, as they threaten sustainability ecological balance environment. The growth population, climate change, expansion industrial processes main causes these issues. Therefore, effective remediation polluted water by means detoxification purification is paramount importance. To this end, nanoscience nanotechnology have emerged viable options that hold tremendous potential toward advancement wastewater treatment methods to enhance efficiency along with augmenting supply via utilization unconventional sources. Materials at nano level shown great promise applications owing their unique physicochemical properties. In focus article, we highlight role new fundamental properties scale material drastically increased due dimension (e.g. volume-surface ratio) impact treatment. We identify discuss how nano-properties could improve three domains remediation: identification pollutants, adsorption catalytic degradation. After discussing all beneficial aspects further key challenges associated nanomaterials for Looking current state-of-the-art, well nanomaterials, believe in future will see a significant materials on many strategies.

This study addresses the critical issue of removing copper(II) ions from water using an eco-friendly approach with natural biomaterials. Alginate, a polysaccharide, is employed as primary adsorption material. The involves conversion alginate into nanoparticles, and ternary blend prepared by mixing nanoparticles carboxymethyl cellulose polyethylene glycol (AL-NPs/CMC/PEG). blend's morphological structural transformations have been comprehensively investigated techniques such DLS, FT-IR, XRD, TGA, SEM. Batch experiments were conducted systematically to investigate crucial parameters, contact time (60–300 min), initial copper concentration (62.5 ppm–1000 ppm), solution pH (2–8), adsorbent dosage (1–5 g). results obtained are highly encouraging, revealing impressive 80.9 % efficiency in removal ions. acquired experimental data then subjected analysis Langmuir Freundlich, isotherm, well pseudo-first pseudo-second-order kinetics studies. outcomes these isotherm models indicated favorable fit Freundlich suggesting strong affinity between metal Furthermore, kinetic studies revealed that process closely adheres kinetics, underlining reliability process. From desorption studies, 0.1 M HCl was extremely effective eluant when compared HNO3 EDTA. It could be reused three appreciate efficiency. research underscores potential for environmentally sustainable address persistent environmental challenge posed ion contamination.
