This innovative article provides a detailed description of the successful biosynthesis zinc nanoparticles (ZnO-NPs) using an aqueous extract Algerian Date Syrup, also known as molasses. A meticulous process was carried out to determine optimal calcination temperature for ZnO-NPs, crucial step in preparation these nanoparticles. The study further extended by creating ZnO/rGOx nanocomposites through hydrothermal method, varying concentrations reduced graphene oxide (rGO) at 5%, 10%, and 15%....
Methylene blue (MB) adsorption was performed on a natural material powder of Cynara scolymus as new inexpensive adsorbent identified by Cs. To analyze the Cs material, FTIR, SEM, isoelectric point (pHpzc) analysis, TGA, and DRX were used. The maximum experimental capacity 203.333, 192.187, 179.380 mg•g−1 at 298, 303, 313 K, respectively. correlation coefficients (R2) average percentage errors APE (%) values for kinetic isotherms models indicated that kinetics followed pseudo-nth order model...
Monitoring stations have been established to combat water pollution, improve the ecosystem, promote human health, and facilitate drinking production. However, continuous extensive monitoring of is costly time-consuming, resulting in limited datasets hindering management research. This study focuses on developing an optimized K-nearest neighbor (KNN) model using improved grey wolf optimization (I-GWO) algorithm predict dry residue quantities. The incorporates 20 physical chemical parameters...
Here, the chemical modification of Ziziphus jujuba stones (ZJS) treated with ortho-phosphoric acid (ZJS-H3PO4) is investigated to enhance its adsorption properties for organic dyes. The physicochemical ZJS-H3PO4 reveal increased porosity (87.29%), slightly higher bulk density (0.034 g mL−1), and enhanced acidity (31.42 m eq g−1) compared untreated ZJS. XRF analysis confirms successful incorporation orthophosphoric during treatment due a significant increase in phosphorus content. maximum...
AbstractA native layered double hydroxide Mg–Al–CO3, denominated LDH, containing Mg(II) and Al(III) in the layers, was prepared by a co-precipitation method. Its calcined form Mg–Al, (CLDH), obtained calcination at 500°C. Both materials were characterized powder X-ray diffraction (PXRD), Fourier transformation infrared spectroscopy, thermogravimetric analysis, determination of point zero charge. The porous structure solids investigated nitrogen adsorption 77 K. adsorptive affinity these for...
The removal of Congo red dye (CR) from aqueous solutions using a novel low-cost biological adsorbent, Stipa tonassicima fibers, has been investigated in this paper. Batch experiments were conducted to examine the effect main parameters, such as initial CR concentration, pH, and temperature on sorption dye. Maximum adsorption was observed at pH 4 biosorption capacity S. tenassicima enhanced by increasing temperature. Rate constants pseudo-first order, pseudo-second intraparticle diffusion...
Cone biomass of Pinus brutia, a novel low-cost adsorbent prepared from forest waste has been utilized as an for the removal Congo red (CR) dye aqueous solution. The adsorbate concentration, pH, time, and temperature were examined in batch tests. Maximum biosorption capacity was 102.8 mg/g, showing that cone P. brutia more efficient than most other adsorbents. Experimental data analyzed by Langmuir, Freundlich, Sips adsorption isotherms models showed process followed model....
Activated carbon (AC) was prepared by means of a novel physiochemical activation method from low-cost biosorbent, agricultural waste (Stipa tenacissima fiber). A two-step pyrolysis considered instead single-step pyrolysis, which involved zinc chloride for the first step and steam mixture water, CO2 acetic acid second step. The obtained AC tested as an adsorbent removal basic dye, Methylene blue (MB) aqueous solutions. Batch experiments were conducted to examine effect main parameters, such...
