Developing an ideal and cheap adsorbent for adsorbing heavy metals from aqueous solution has been urgently need. In this study, a novel, effective and low-cost method was developed to prepare the biochar from lettuce waste with H3PO4 as an acidic activation agent at a low-temperature (circa 200°C) hydrothermal carbonization process. A batch adsorption experiment demonstrated that the biochar reaches the adsorption equilibrium within 30 min, and the optimal adsorption capacity of Cd(II) is 195.8 mg⋅g-1at solution pH 6.0, which is significantly improved from circa 20.5 mg⋅g-1 of the original biochar without activator. The fitting …

Treatment of nitrate-rich wastewater is important but challenging for the conventional biological denitrification process. Here, we propose combining the electrochemical reduction and anaerobic ammonium oxidation (anammox) processes together for treatment of nitrate-rich wastewater. This article reviews the mechanism and current research status of electrochemical reduction of nitrate to ammonium as well as the mechanism and applicability of the anammox process. This article discusses the principles, superiorities, and challenges of this combined process. The feasibility of the combined process depends on the efficiency of electrochemical nitrate reduction to ammonium and the conditions in the anammox process to use the reduced ammonium …

A novel fabrication method for modifying alkaline lignin (AL) was reported, in which trimercapto-s-triazine trisodium salt was used as a modifier to tune surface properties of AL. Molecular structure of modified AL (FAL) was determined by 3D-EEM, synchronous fluorescence, FTIR, 13C MAS NMR and XPS. Two-dimensional correlation spectroscopy and electron localization function demonstrated that both of electrostatic and coordinate bonds formed between these functional groups and Pb(II) at higher pH of 3.0 to 6.0 while only coordinate bond at lower pH of 0.2 to 1.2. The higher the solution pH was, the stronger the adsorption capacity of FAL had. The …

Land application of swine manure slurry is a common practice to supplement nutrients to soil for crop production. This practice can introduce antibiotic residues and antibiotic resistance genes (ARGs) into the environment. Field testing is critical in identifying manure management practices effective in minimizing the environmental impacts of manure-borne antibiotic and ARGs. The objective of this study was to determine how the timing of swine manure application relative to rainfall events impacts the fate and transport of antibiotics and ARGs in surface runoff and manure-amended soil. Swine manure slurry was either broadcast or injected on test plots in the field. …

In recent years, application of biochar for removal of pollutants from aqueous solutions has been of interest due to favorable physicochemical properties and availability of feedstock. However, adsorption behavior has been reported only for raw and micro biochar particles and taking advantage of biochar nanoparticles, which offer superior specific surface area, did not receive any attention. The objective of this study was to investigate the adsorption efficiency of produced nanobiochar from pinewood. For this purpose, removal of carbamazepine (CBZ), a globally prescribed pharmaceutical, at very low concentrations (0.5–20 ppb) on as-produced nanobiochar with average particle size of 60 nm was …
Feasibility Of Electromagnetic Soil Heating Using Magnetic Nanoparticle-Coated Geotextiles, Ijung Kim, Caroline Best, Seunghee Kim
Feasibility Of Electromagnetic Soil Heating Using Magnetic Nanoparticle-Coated Geotextiles, Ijung Kim, Caroline Best, Seunghee Kim
Department of Civil and Environmental Engineering: Faculty Publications
This paper reports a new way of soil heating using a woven and a non-woven geotextile coated with magnetic nanoparticles (MNPs) that generate heat when exposed to a magnetic field. The MNPs were synthesised in the presence of the geotextile, creating and simultaneously coating the MNPs onto the geotextile. The fixation of MNPs on the geotextile was confirmed by direct observation by way of scanning electromagnetic images and an induction heating test. When the prepared geotextile was placed inside a soil medium, heat was generated immediately as the geotextile was exposed to a high-frequency alternating magnetic field, subsequently transferring heat …

Diclofenac (DCF) is a prevalent anti-inflammatory drug used throughout the world. Intensive researches carried out in the past few decades have confirmed the global ubiquity of DCF in various environmental compartments. Its frequent occurrence in freshwater environments and its potential toxicity towards several organisms such as fish and mussels makes DCF an emerging environmental contaminant. At typical detected environmental concentrations, the drug does not exhibit toxic effects towards living organisms, albeit chronic exposure may lead to severe effects. For DCF, about 30–70% removal has been obtained through the conventional treatment system in wastewater treatment plant being the major primary sink. …

Adsorptive membranes have many applications in removal of contaminants, such as heavy metals and organic contaminants from water. Recently, increasing concentrations of pharmaceutically active compounds, especially antibiotics, such as chlortetracycline in water and wastewater sources has raised concerns about their potentially adverse impacts on environment and human health. In this study, a series of polyacrylonitrile (PAN)/activated biochar nanofibrous membranes (NFMs) with different loadings of biochar (0–2%, w/w) were fabricated using electrospinning. The morphology and structure of fabricated membranes was investigated by scanning electron microscopy, Fourier transform infrared and thermogravimetric analysis. The results showed that at 1.5% of biochar loading, the …
