Mining wastewater can have adverse effects on the ecosystem; thus, treatment before discharging into environment is of utmost importance. This manuscript reports effect mining environment. Moreover, currently used, effective and commercialised mine technologies such as SAVMIN®, SPARRO®, Biogenic sulphide, DESALX® are reported in this study. These integrate two or more separation processes, which been proven to be for high recovery salts water reuse. Some significantly recover >95% water. Modern pilot-stage laboratory-scale systems used removal metals also herein. Since some generate highly toxic sludge other waste products, management generated was considered. studies focused at laboratory level using adsorption process. Most adsorbents exhibit promising results; however, there insufficient research reusability, management, economic analysis systems. implementation necessary. Furthermore, integration precious low concentrations desirable addition reclamation achieve circular

Abstract In the era of industrialization, chromium (Cr) as a metal poses substantial threat to ecosystem. Selenium (Se) is essential for minimizing heavy stress in crops and effectively reducing their accumulation edible plant parts. This research work aimed evaluate synergistic effect compost Se alleviation Cr chili plants. A greenhouse trail was conducted investigate individual combined effects foliage applied selenium (Na 2 SeO 4 = 3 µM) soil (250 mg kg −1 , w/w) on growth, physio-biochemical, antioxidant grown under varying levels induced (0, 100, 200 using K O 7 ). Findings revelaed that significant linear reduction observed biomass, physiological parameters with an increasing level concentrations. Maximum decrease relative water content (20.04 27.21%) total chlorophyll concentrations (11.73 20.57%) increased electrolyte leakage (59.14 130.52%) at 100 comparison control, respectively. Combined application showed increase regardless soil. Synergistic approach improved growth sole limiting movement uptake roots fruits Moreover, potential plants helped cope higher by lipid peroxidation membrane damange. The use induces physio-biochemical defense responses against promising highlights growing crop Cr-contaminated soils achieve better quality yields.

Abstract Environmental and occupational exposure to hexavalent chromium (CrVI) is mostly renowned as a possible hepatotoxic in mammals. Echinacea purpurea (L.) Moench, phenolic-rich plant, recurrently used for its therapeutic properties. Therefore, this investigation was done explore whether E. (EP) root extract would have any potential health benefits against an acute dose of CrVI-induced oxidative damage hepatotoxicity. Results revealed that GC–MS analysis EP has 26 identified components with significant amount total phenolic flavonoid contents. Twenty-four Male Wistar rats were divided into four groups: control, (50 mg/kg BW/day 21 days), CrVI (15 BW single intraperitoneal dosage), + CrVI, respectively. Rats treated displayed remarkable rise stress markers (TBARS, H 2 O , PCC), bilirubin, lactate dehydrogenase activity, marked decrease enzymatic non-enzymatic antioxidants, transaminases, alkaline phosphatase activities, serum protein level. Also, administration induced apoptosis inflammation addition histological ultrastructural abnormalities the liver tissue. The examined parameters improved significantly pretreated then intoxicated CrVI. Conclusively, had potent antioxidant activity could be modulation

A novel Cr-doped BaTiO3 aerogel was successfully synthesized using a co-gelation technique that involves two metallic alkoxides and supercritical drying method. This freshly prepared has high specific surface area of over 100 m2/g exhibits improved responsiveness to the simulated sunlight spectrum. Methyl orange (MO) chosen as pollutant, results reveal aerogel, when modified with noble metal silver (Ag), achieves pollutant removal rate approximately 3.2 times higher than commercially available P25, reaching up 92% within 60 min. The excellent photocatalytic performance Ag-modified can be primarily attributed its extensive three-dimensional porous architecture. Furthermore, incorporation Ag nanoparticles effectively suppresses recombination photo-generated electrons holes. Stability reusability tests have confirmed reliability aerogel. Therefore, this material emerges highly promising candidate for treatment textile wastewater.

Biological treatment is currently a favorable option to treat wastewater due its environmentally friendly methods and minimal toxic by-products. The majority of biological uses bacteria as agents, which are known have excellent capabilities for removing various pollutants. Researchers extensively explored the use extracellular polymeric substances (EPSs) generated by in treatment. This review focuses on sources EPSs, factors influencing their production, role Bacterial species, nutrient availability, pH, temperatures, presence toxins were mentioned be EPS production Produced EPSs may promote aggregation, adsorption, decolorization, degradation highlights challenges discovering new potential bacterial species complex extraction methods, well importance mass larger-scale applications.

Abstract Nitrogen‐rich graphene oxide/polyvinyl alcohol (PGOPA) composites were synthesized through the coupling and Schiff base reactions of oxide (GO) with polyvinyl (PVA) polyethyleneimine (PEI). Fourier‐transform infrared spectroscopy (FTIR), Energy dispersive (EDS) X‐ray photoelectron (XPS) analyses confirmed successful preparation PGOPA. The maximum adsorption capacities 680.3 mg/g at 298 K, 694.4 308 704.2 318 exceeding those most previously reported GO‐based materials. PGOPA exhibited excellent cycling stability, retaining 87.2% its initial capacity after six consecutive adsorption–desorption cycles. In absence competing anions (SO 4 2− PO 3− ), showed remarkable selectivity for Cr(VI). Adsorption experiments isotherm Cr(VI) followed Langmuir model. pseudo‐second‐order model fitted this process well, indicating chemisorption characteristics. XPS revealed that mechanism primarily involved electrostatic interactions reduction to Cr(III). This work provides valuable technical support structural design highly selective adsorbents removal from wastewater.
