Biochar from peanut shell was used as the precursor for preparation of porous biochar by KOH activation.The pore structures also were characterized scanning electron microscopy (SEM) and N2 adsorption/desorption.The adsorption performance removal methylene blue (MB) deeply investigated.The effects impregnation ratio (KOH/biochar: w/w), activation temperature, time on evaluated.In addition, initial MB concentration pH value process studied.The optimum conditions preparing obtained with 1.5:1...
With the rapid global proliferation of electric vehicles (EVs), their integration as a significant load component within power systems increasingly influences stable operation and planning electrical grids. However, high uncertainty randomness inherent in EV users’ charging behaviors render accurate forecasting challenging task. In this context, present study proposes Particle Swarm Optimization (PSO)-enhanced Long Short-Term Memory (LSTM) network model. By combining search capability PSO...
Biochar has been studied for remediation of heavy metal-contaminated soils by many researchers. When in external conditions, biochar ages, which can transform its structural properties and adsorption capacity. This study was conducted with two oxidation processes, HNO3/H2SO4 NaOH/H2O2, to simulate the effects acid alkaline soil conditions. The results show that oxygen-containing functional groups increased aged biochar, led improve ratio oxygen carbon (O/C). Nitro were found acid-oxidation...
In this study, ozonation treatment of C.I. Reactive Black 5 (RB5) was investigated at various operating parameters. The results showed that the aqueous solution initially containing 200 mg/L RB5 quickly decolorized pH 8.0 with an ozone dose 3.2 g/h. Reaction intermediates m/z 281, 546, 201, 350, 286 and 222 were elucidated using liquid chromatography-mass spectrometry, while sulfate ion, nitrate ion three carboxylic acids (i.e., oxalic acid, formic acetic acid) identified by exchange...
Magnetic nitrogen-doped porous carbon (MNPC) has been prepared via self-catalytic pyrolysis of bimetallic metal-organic frameworks (MOFs). The as-obtained MNPC showed favorable features for antibiotics adsorption such as high specific surface area (871 m2 g−1), pore volume (0.75 cm3 structure, good graphitization degree, and rich N-doping. Moreover, the magnetic properties due to Co species, which is embedded with a dispersion, so absorbent can be easily separated. Based on above excellent...
Abstract Optimized calculation of 209 PCBs was carried out at B3LYP/6‐31G* level in Gaussian98 program to obtain their structural parameters. It found there is significant correlation between the Cl substitution position and some parameters such as α ( r 2 =0.9972), E HOMO =0.8874) etc. Consequently numbers positions N ) were taken theoretical descriptors establish novel QSPR model for predicting n ‐octanol/water partition coefficients (log K ow all PCB congeners, which can be used directly...
High‐purity KTa 0.3 Nb 0.7 O 3 nanoparticles have been successfully synthesized by hydrothermal and solvothermal methods. The KOH concentration the solvent composition significant effects on final products. synthesis mechanism was discussed. X‐ray diffraction, scanning electron microscopy, transmission microscopy investigations show that typical samples solvothermally are nanosized, well crystallized, single crystalline. shows a pseudo‐cubic to tetragonal transition with increasing...
We have investigated the effect of electrical conductivity constituents on poling behaviour ceramic inclusions in 0–3 ferroelectric composites which comprise a dilute suspension spherical particles uniformly distributed matrix material. A new model for pyroelectric and piezoelectric properties terms conditions (poling field time) has been developed to include conductivity. Simulated results show that plays an important role process. Properly increasing σm can enhance polarization inclusion...
In this work, the hierarchically porous biomass carbon (HPBC) was originally prepared for desalination through a simple activation of cheap (BC). Such crucial activated conditions as KOH/C ratio, time and temperature were deeply investigated. It is demonstrated that had great influence on structure properties electrochemical performance. According to surface analyses, HPBC with larger area hierarchical could be well obtained in suitable conditions. The analyses showed increased...
