Abstract The removal of arsenic from drinking water by nanofiltration membranes was investigated. Experiments were conducted with tap water to which arsenate and arsenite were added. Two types of nanofiltration membranes, i.e., NF‐90 and NF‐200, have been tested. The effect of various operating cond...

The contamination of groundwater by leached out arsenic has assumed an alarming proportion in several countries. Continued and prolonged ingestion even at a very low level can lead to serious arsenic-related diseases. Strong epidemiological evidence of arsenic carcinogenicity has forced the World He...

Exposure to heavy metals is believed to cause toxic health effects in human and other life forms on earth, even at trace level. Thus, effective removal of those undesirable metals from water systems is still a very important and challenging task. The burgeoning demand for clean water has led to the ...

Adsorption using nanomaterials is considered an effective method for controlling the levels of toxic heavy metal in wastewater. Herein, a novel adsorbent, core-shell phase-transited lysozyme film-coated magnetic nanoparticles (Fe3O4@SiO2@PTL) for Hg(II) ions removal from aqueous solutions was explor...

In the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without si...

We synthesized three new dithiocarbamate (DTC)-modified cellulose biomaterials (DMC-1, DMC-2, and DMC-4) to investigate their adsorption capabilities as mitigators of arsenite (AsIII) in aqueous media. The main novelty of the adsorbents was that, among two inorganic species of arsenic, arsenite and ...

Developing cost-effective metal/metal oxides for peroxymonosulfate (PMS) activation remains a key issue in the sulfate radical based advanced oxidation process. In this work, electroplating sludge (ES), a transition metal-rich byproduct, was anaerobic calcined and characterized. Then, calcined elect...

In this study, the impact of a catalyst's surface acidity on supercritical water gasification (SCWG) of glucose is investigated. Four different catalysts including Ni, Ru0·2Ni, Ru0·5Ni and NiLa were prepared on an Al2O3 support via an incipient impregnation method. NH3-TPD and pyridine-FTIR results ...

Rainwater discharge and human impacts produce wastewater, which is a contaminated type of water. Sediments also discharge phosphate into the water column when there is a lack of dissolved oxygen in the water. Through the manufacturing of environmentally benign nanoparticles, nanotechnology may reduc...

Environmental context It is practicable to remediate chlorobenzene-contaminated groundwater by in situ chemical oxidation. This study shows highly efficient degradation of chlorobenzene by an Fe-based process in a wide range of pH values. The technology is feasible for the removal of chlorobenzene f...

Sand filters devised with iron-rich adsorbents are extensively promoted and deployed in the arsenic-prone south and south-east Asian countries (e.g., Bangladesh). The approach offers superior performance in removing arsenic while the spent sludge from the sand filters is an issue of concern due to t...

Rapidly expanding use of nanoparticles in every discipline of life necessitates finding their potential to increase food production to match with burgeoning population. This study was conducted first time in Bangladesh to determine the potentiality of iron nanoparticles for enhancing germination and...

This study assessed the functionality of metallic iron (Fe0) filtration systems using porous iron composite (PIC) as an alternative to granular Fe0/aggregate mixtures. The usage of PIC for water treatment has many challenges which are related to the well-drained nature of highly porous filters and t...

The principle of subsurface or in situ iron and arsenic removal is that aerated water is periodically injected into an anoxic aquifer through a tube well, displacing groundwater containing Fe(II). An oxidation zone is created around the tube well where Fe(II) is oxidised. The freshly formed iron hyd...

The ACF-cathode/Co2+/PDS system was validated to effectively remove sulfamethoxazole (SMX), a typical carcinogenic and refractory antibiotic from the aqueous environment. The experimental conditions such as initial pH, PDS, Co2+ concentrations, and current density were optimized. Moreover, the syste...
