Abstract Green and efficient agro-waste-based activated carbon has been prepared utilizing peanut shells for adsorptive elimination of an industrial dye, methylene blue, lead from polluted water. The carbonaceous biomass obtained was chemically using either NaOH, ZnCl 2 , or steam characterized by scanning electron microscopy, Fourier-transform infrared spectroscopy, N adsorption desorption studies. process optimal blue at alkaline pH, while pH 4.5 Pb (II) adsorption. takes place through pseudo-second-order kinetic, the rate-governing step procedure are intraparticle diffusion film diffusion. Furthermore, thermodynamics studied, Gibbs free energy (ΔG°) values negative (− 35.90 to − 43.59 kJ mol −1 ) indicating spontaneous investigated pollutants on carbon. As per correlation coefficient, results were best fit Langmuir isotherm with maximum capacity 303.03 mg g 130.89 (II). successfully removed %removal exceeding 95%. mechanisms interaction is a combination electrostatic ion exchange, interacts via π–π interaction, hydrogen bonds, interaction. Thus, employed decontaminate wastewater groundwater samples. developed promising, cost-efficient, green, accessible tool water remediation.

Non-essential heavy metals (HMs) are one of the most toxic substances released into environment, affecting food chain and posing a threat to security. The research data was collated after carefully observing some studies conducted on commonly consumed products highlighting metal exposure pathways crops techniques adapted quantification HMs in chain. tools developed estimate ecological health risks induced via ingestion HM-contaminated both children adults India discussed. It is observed that Cd, Cr, Cu, Pb, Zn studied products. Bioaccumulation indices Indian revealed varying intake. Children suffer more from consuming contaminated with than adults. This review summarizes distribution HMs, their pollution, correlation between each HM concentration.

A new method using fluorescence was developed to detect Hg 2+ ions in water. This relied on the reaction between NH 2 ‐MIL‐53(Al) and 5‐bromo‐2‐hydroxyacetophenone. The carefully fine‐tuned for optimal conditions analytical parameters like pH levels, nanosensor quantity, detection limits. It showed great linearity detecting range of 0.0–3.0 ppm (0.0–1.50 × 10 −5 M), with a very low limit 1.65 −2 (8.23 −8 M). We tested how well can distinguish different substances by investigating whether other common water samples would interfere. results were positive, as presence these did not significantly affect accuracy ions, confirming method's reliability. In order confirm its dependability, we conducted quantitative test samples. recovery rates obtained ranged from 97.16% 103.2%, demonstrating precision accuracy. comparison inductively coupled plasma optical emission spectrometry (ICP‐OES), well‐known analyzing trace metals, produced similar results, further instilling confidence 5Br2HA = N‐Al‐MOF that developed. general, this research emphasizes exciting potential various cosmetic provides strong dependable alternative traditional methods.

Abstract This study describes the development of a multifunction chromoionophoric probe‐based nano‐conjugate material for colorimetric determination, recovery, and removal palladium cobalt ions (Pd(II) Co(II)) from electronic wastes electroplating wastewater. The was prepared using building‐block approach by anchoring 4‐[(E)‐(2‐hydroxyphenyl)diazenyl]‐1‐nitrosonaphthalen‐2‐ol (HDN) organic probe onto nano‐spherical silica carrier. materials were characterized different techniques, such as TEM, SEM XRD, BET. HDN evaluated its effectiveness in detecting removing Pd(II) Co(II) wastewater testing various parameters pH, sensing system temperature, reaction kinetic, amount, stability existence other coexisting metal ions. demonstrated high selectivity sensitivity ion‐sensing ions, with detection limit 7.18 208 nM, respectively. method displayed optimal at pH levels 6.0 8.0 respectively, presence did not meaningfully influence performance ion‐detection due to powerful ability material. adsorption capacity towards investigated outcomes 163.40 128.57 mg/g, could be regenerated eluting adsorbed 0.15 M HCl solution. In addition, reused multiple times, almost no decrease initial after regeneration. Based on findings, shows potential environmental removal, wastewater, indicating multi‐function solution concerns issue even commercialized used larger scale.
