Novel iron activated biochars (FA-BCs) were prepared via simultaneous pyrolysis and activation of FeCl3-pretreated bermudagrass (BG) for removing microcystin-LR (MC-LR) in aqueous solution. Compared to the raw BC (without activation), surface area adsorption capacity FA-BC at impregnation ratio 2 (2 g FeCl3/g BG) enhanced from 86 m2/g 0.76 mg/g 835 9.00 mg/g. Moreover, possessed various oxides ...
Combined adsorption and oxidation using biochar to activate persulfate has been recently applied remove contaminants, yet most of the experiments are carried out artificial synthetic water instead real waters. Here we tested removal humic substances which is abundant affecting quality in natural waters, by combined with corn stalk biochar. Results showed that, compared prepared at 400 °C, 600 °...
The development of efficient heterogeneous persulfate activators is one the main research topics in wastewater treatment area. present work deals with activation sodium (SPS) using nickel oxide/strontium carbonate (NiO/SrCO3) for degradation sulfamethoxazole (SMX), a representative compound from group antibiotics. Results showed that NiO/SrCO3 exhibited high performance towards SPS, leading to ...
Introduction: The most important affect of natural organic matters in water is their reaction with chlorine and producing of disinfection byproducts that are carcinogenic. Humic acid is most common natural organic materials of surface water. Advanced oxidation processes (AOPs) are methods for the removal of organics from aqueous solutions. Application of electron beam radiation is one of these ...
In this work, we synthesized a trypsin-stabilized fluorescent gold nanocluster. It was found that sulfide interacted with the nanocluster, which could result in significant fluorescence quenching. With this quenching effect, a fluorescence sulfide sensor was developed. This sensor responded linearly to sulfide in the range of 50 nM to 8 μM, and was capable of detecting sulfide as low as 5.5 nM....
Photocatalytic materials for photocatalysis is recently proposed as a promising strategy to address environmental remediation. Metal-free graphitic carbon nitride (g-C3N4), an emerging photocatalyst in sulfate radical based advanced oxidation processes. The solar-driven electronic excitations g-C3N4 are capable of peroxo (O?O) bond dissociation peroxymonosulfate/peroxydisulfate (PMS/PDS) and ox...
