Abstract Elevated concentrations of heavy metal ions are in many ways considered to be an affront the aquatic ecosystems; their sources being attributed mainly industries and agricultural sectors and, a lesser extent, urban water runoff during storms. Heavy that easily found include lead, mercury, chromium, cadmium, arsenic, copper. These metals, if ingested or inhaled, cause health hazards present great risks bodies because they reduce oxygen available fish other animals. One way prevent this problem is use nanoparticles at nano level obtained from industrial waste products for removal metals water. In adsorption process, tend attach exterior surfaces these nanoscale biomass particles, with possible aqueous phase. They also affirmed technical effectiveness nanowaste desalination reduces availability contaminants relatively cheaper more sustainable manner than conventional methods. study, synthesized (45–60 nm) pomegranate (PGSN) were used as biosorbents, which yielded high performances 85% Fe²⁺ 83% Ni²⁺ ions. The biosorbent was characterized using zeta size potential analyses, Field Emission Scanning Electron Microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), Energy Dispersive X-ray Analysis (EDXA), Brunauer-Emmett-Teller (BET) surface analysis, High-, diffraction (XRD).

The use of living Arthrospira platensis (A. platensis) cultures emerges as a promising green solution for the bioremediation water contaminated by toxic metal waste. scope present study is to evaluate microalga’s potential in heavy remediation, case multi-metal-treated (multi-MT) systems. For this reason, A. were exposed mono- and multi-metal solutions Cu, Cd, Ni, Pb, Zn, their adsorption ability was investigated. removal efficiency evaluated using atomic absorption spectroscopy (AAS). Additionally, examined Fourier transform infrared (FTIR) spectroscopy, Near-Infrared (NIR) Spectroscopy, UV-Vis spectrophotometry, optical microscopy, together with pH electrical conductivity (EC) measurements quality changes induced stress. results showed that still efficient multi-MT cultures. In particular, Zn elevated or relative respective mono-metal-treated (mono-MT) cultures, showing synergistic cooperative interaction between metals, while Ni decreased compared mono-MT an antagonistic other metals. shows considered effective microalga toward polluted

Heavy metal contamination in water sources poses a significant threat to environmental and public health, necessitating effective remediation strategies. Nanomaterial-based approaches have emerged as promising solutions for heavy removal, offering enhanced selectivity, efficiency, sustainability compared traditional methods. This comprehensive review explores novel nanomaterial-based remediation, focusing on factors such regeneration, scalability, practical considerations. A systematic literature search was conducted using multiple academic databases, including PubMed, Web of Science, Scopus, identify relevant articles published between 2013 2024. The identifies several nanomaterials, graphene oxide, carbon nanotubes, metal-organic frameworks, which exhibit high surface areas, tunable chemistries, excellent adsorption capacities. Surface functionalization with specific functional groups (e.g., carboxyl, amino, thiol) significantly enhances the selectivity target ions. Advances regeneration strategies, chemical desorption, electrochemical photocatalytic improved reusability cost-effectiveness these materials. Scalability remains critical challenge, but recent developments synthesis methods, green continuous-flow synthesis, offer large-scale production. stability longevity nanomaterials been through modification development hybrid nanocomposites. Integrating existing treatment infrastructure combining them other techniques, membrane filtration can enhance overall efficiency feasibility. In conclusion, hold immense promise revolutionizing advancing sustainable management practices. As future research is geared towards retrofitting plants, it equally mitigate unintended health consequences associated widespread production use their leachability into systems persistence.

Abstract This experiment was conducted to evaluate the adsorption–desorption characteristics and mechanisms of heavy metals by mealworm frass (MF). The adsorption Cd MF were predominantly influenced initial pH, dosage, temperature, reaction time. maximum capacity 48.1 mg/g, which well described Langmuir isotherm pseudo-second-order models. optimal desorption solution for separating from Cd-adsorbed 0.02 M HCl, showed a high efficiency over 90%. In particular, mechanism confirmed through functional group change, cation exchange, precipitation experiment, it found that affected exchange on surface. amounts fractionated F1 (exchangeable) F2 (bonded carbonate) solutions 58.9 25.2% total amount, means adsorbed can be easily eluted/mobilized environmental changes. Considering above results, is believed used as an effective adsorbent remove Cd. However, since sensitive changes bond itself weak, considered special management plan needed.
