Halophilic Biodegradation of 3-Nitro-1,2,4-Triazol-5-One in Brine
(ASCE, 7/4/2023 1)Production of insensitive munitions (IM) creates wastewater containing 3-nitro-1,2,4-triazol-5-one (NTO). Because NTO is an anion in neutral pH wastewaters, it can be removed via ion exchange (IX), released during IX brine ... -
Optimization of Electro-Charge Loading in Electrocoagulation Using Response Surface Methodology for the Abatement of Salicylic Acid from Wastewater
(ASCE, 6/26/2023 )The present investigation demonstrates a batch electrocoagulation (EC) process performance for the abatement of salicylic acid–laden wastewater. The electro-charge loading optimization was assessed using response surface ... -
Electrochemical Detection of Nitenpyram Pesticide Using Nanoparticles Synthesized from Waste Plastics
(ASCE, 5/29/2023 )In this study, silver nanoparticles (AgNs) were prepared using new methodology, and carbon quantum dots (CQDs) were prepared from waste plastics. For nitenpyram analysis, modified electrodes based on CQDs/AgNs/ sodium ... -
Evaluating the Effect of Nonaerobic Hydraulic Retention Time on Nutrients Removal in Nonaerobic and Aerobic SBR
(ASCE, 5/26/2023 )The nonaerobic stage is critical for the processes of denitrification and phosphorus release in biological wastewater treatment. A lab-scale sequencing batch reactor (SBR) operating as nonaerobic/aerobic was used to treat ... -
Mesoporous Material Modified by Poly-O-Phenylene and Aquatic Plants Cellulose for Effective Removal of Hg(II) Ions
(ASCE, 7/24/2023 )In this work, a composite adsorbent (modified poly-o-phenylene aquatic plant cellulose; MPP-AC) was prepared by using aminated mesoporous material as the carrier, aquatic cellulose as the dopant, and supporting ... -
Potential of Thermal Desorption Residue of Oil-Based Drilling Cuttings for Use in Subgrade Materials
(ASCE, 7/31/2023 )The high content of silicon and aluminum present in the thermal desorption residue of oil-based drilling cuttings (ODCR) makes it potentially suitable for use in subgrade materials. The main components of ODCR are akin to ... -
Adsorption Performance and Mechanism of Phosphate in Water by Magnesium Oxide-Corncob Biochar
(ASCE, 7/10/2023 )In this study, magnesium oxide-corncob biochar (MgO-CB) was prepared by MgCl2 modified corncob biomass for the adsorptive removal of phosphate from water. The adsorbents were characterized by scanning electron microscopy ... -
