A self-adhesive PAA ionic hydrogel was used to fabricate highly efficient and flexible moisture-induced electricity generators, which can directly harvest electrical energy from atmospheric moisture.
This study presents a rapid and straightforward method to prepare multifunctional hydrogel using deep eutectic solvent-pretreated lignin (DESL), aluminum ions (Al 3+ ), polyacrylic acid (PAA) in an aqueous system.
Ozonation was used for tertiary treatment of hardwood KP bleaching effluent. The objectives were to investigate the performance ozonation on reduction recalcitrant COD and color in biologically treated effluent change biodegradability during process. results indicate that removal enhanced by increasing solution pH temperature, but not completely removed from due ozone-resistant substances remain after treatment. more effective decoloration than removal. highest efficiency 99% 55% at 11.7 25...
Lignin is a promising material due to its excellent properties. It commonly used in electrochemical energy systems (including electrolytes, electrodes, diaphragms, and binders) low price, sustainability rich functional groups. However, lignin’s applications storage have not been systematically reviewed the current research. In this article, recent advances preparation design of lignin-derived materials were reviewed. Starting with brief overview basic chemistry lignin separation process,...
The influence of residual black liquor in pulp on wastewater pollution after the bleaching process was studied. results show that CODCr effluent has a remarkable linearity with loss pulps without liquor. For some liquor, more than 34% overall is produced by It follows effective washing to reduce an appropriate way control pollutant discharges from and paper mill industry.
The influences of stock consistency on the kappa number, residual alkali pulp, flow direction lignin, chemical oxygen demand, oxidation with dichromate (CODCr), and five-day biochemical demand (BOD5) in effluents were investigated a washing process. Compared 15% consistency, 35% could lead to decrease at least 25% consumption water while cutting 75.27% 46.29% CODCr BOD5 effluents, respectively. Moreover, lignin reduced greatly from 39.35 g·t-1 12.76 g·t-1, which will be beneficial treatment...
Hardwood KP bleaching effluents, before (influent) and after (effluent) biological treatment, were characterized compared to identify the main bio-recalcitrant organic compounds in effluent. The results indicate that treatment reduces CODcr BOD5 by 67% 88%, respectively. However, various still retained biologically-treated effluent, which exhibits an increase effluent color. Spectroscopic analysis suggests colored substances are most recalcitrant materials Di-n-octyl phthalate...
Abstract Paper mill effluent has been characterized as recalcitrant because of containing lignin and its derivatives. Since biofilm system exhibits a notable potential for the removal contaminants, sequencing batch reactor (SBBR) was employed to treat coagulated recycled paper in this study. The results indicated that SBBR removed 91.3 % chemical oxygen demand (COD), whilst total suspended solid (TSS) color reached 83.1 71.0 %, respectively. microbial analysis suggested three typical...
Abstract The wavelengths and transition rates of W 40+ -W 42+ ions within the range 40–140 Å, have been calculated using Flexible Atomic Code Dirac-Fock-Slater method with a central potential. We investigated charge state distribution 38+ 45+ at different temperatures by constructing an appropriate rate equation demonstrate importance dielectronic recombination process. Additionally, we simulated emission spectra in Tokamak plasma environment collisional-radiative modeling. Our findings...
ABSTRACT In this study, three sequencing batch biofilter granular reactors (SBBGRs) were employed to treat model lignin wastewater containing different models (2,6-dimethoxyphenol, 4-methoxyphenol, and vanillin). After 40 days of cultivation, uniform-shaped aerobic sludge (AGS) was successfully developed through nutrient supplementation with synthetic wastewater. During the acclimation stage, chemical oxygen demand (COD) reduction efficiencies showed a trend initial decreasing (5–20%) then...
Abstract Aerogels are essential and effective materials for oily pollution adsorption recovery. This work described a hydrophobic modified cellulose aerogel using waste palm leaf its oil mechanism. By chemical vapor deposition, Methyltrimethoxysilane (MTMS) was employed as modifier of at 80 °C 5 h, the demonstrated exceptional stable hydrophobicity with water contact angle 132.4° that can still be maintained above 120° after two months air exposure. After 10 extrusion cycles, kerosene...
