Rapid growth in population, industry, urbanization and intensive agriculture have led to soil water pollution by various contaminants. Nanoremediation has become one of the most successful emerging technologies for cleaning up contaminants due high reactivity nanomaterials (NMs). Numerous publications are available on use NMs removing contaminants, efficiencies often improved modifications with polymers, clay minerals, zeolites, activated carbon, biochar. This paper critically reviews current state-of-the-art used sustainable remediation, focusing their applications novel remedial approaches, such as adsorption/filtration, catalysis, photodegradation, electro-nanoremediation, nano-bioremediation. Insights into process performances, modes deployment, potential environmental risks management, consequent societal economic implications using remediation indicate that widespread acceptance nanoremediation requires not only a substantial advancement underpinning science engineering aspects themselves, but also practical demonstrations effectiveness already recognized approaches at real world in-situ conditions. New research involving green nanotechnology, nano-bioremediation, risk assessment NMs, outreach activities needed achieve regional global scales.

Clean and safe water is a fundamental human need for multi-faceted development of society thriving economy. Brisk rises in populations, expanding industrialization, urbanization extensive agriculture practices have resulted the generation wastewater which not only made dirty or polluted, but also deadly. Millions people die every year due to diseases communicated through consumption contaminated by deleterious pathogens. Although various methods treatment been explored last few decades their use restrained many limitations including chemicals, formation disinfection by-products (DBPs), time expensiveness. Nanotechnology, manipulation matter at molecular an atomic level craft new structures, devices systems having superior electronic, optical, magnetic, conductive mechanical properties, emerging as promising technology, has demonstrated remarkable feats fields treatment. Nanomaterials encompass high surface volume ratio, sensitivity reactivity, adsorption capacity, ease functionalization makes them suitable application In this article we reviewed techniques being developed using nanotechnology based on biosorption, nanofiltration, photocatalysis, sensing technology. Furthermore, review highlights fate nanomaterials well risks associated with use.

Heavy metal pollution has threatened the ecological environment and human health, therefore, effective removal of these toxic pollutants from various complex substrates is great significance. So far, adsorption still one most approaches. Metal-organic frameworks (MOFs), which are porous crystalline materials consisting ions or clusters organic ligands through coordination bonds. Due to their high surface area, porosity, as well good chemical/thermal stability, have recently attracted attention in environmental analytical chemistry. This review mainly focused on recent studies about applications UiO series MOFs composites emerging MOFs, been used effectively for diverse heavy a variety samples novel materials. Moreover, an elaboration UiO-MOFs its including synthetic methods were presented detail. In addition, characteristics mechanism solid sorbents discussed, isotherms equation, thermodynamics, kinetics. To this end, developing trends MOF-based had also prospected. will provide new idea study development high-performance media efficient wastewater.

Raw date seeds, as prospective natural, broadly obtainable and low-price agricultural waste for adsorbing cationic dyes from aqueous solutions, have been studied. In this work, Iraqi seeds were prepared characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy Brunauer–Emmett–Teller (BET) surface area analysis before being used an efficient bio-adsorbent methyl violet (MV) dye removal. Adsorption tests conducted with three investigated parameters, namely, time of contact, first adsorbate concentration adsorbent dose. Compared the pseudo first-order model (coefficient determination = 0.9001), second-order was determined to be best-fitting a coefficient (R2) 0.9917. The equilibrium isotherms MV obtained, their ultimate capacity adsorption (59.5 mg g1). Two isotherm models, Langmuir Freundlich, studied fit data. Freundlich (R2 0.8154), functioned better R2 0.9837. addition, process endothermic spontaneous. acted active adsorbents remove solutions in experiments.

Abstract Magnetic Fe 3 O 4 nanoparticles (NPs) were successfully synthesized via co-precipitation method using ferric chloride and ferrous sulphate as the starting materials. The shape size of NPs controlled by different types additive including ammonium hydroxide sodium hydroxide. results revealed that adding hydroxide, particles attained a spherical with uniform size. On other hand, turned from to cubic magnetic showed both samples hysteresis loop, which indicated have ferromagnetic behavior. In addition, higher adsorptive behaviour towards Congo red compared NPs, is attributed enhancement their properties. adsorption onto was best described Langmuir isotherm model, while followed Freundlich model.
