Adsorptive Removal of Basic Green Dye from Aqueous Solution Using Humic Acid Modified Magnetite Nanoparticles: Kinetics, Equilibrium and Thermodynamic Studies

Sustainable Dye Adsorption Using Novel Activated Carbon Prepared from Passion Fruit (Passiflora edulis) Leaf: Mechanism and Cost Analysis

“…The results obtained for the AB113 adsorption using NaOH-PFL and the MB dye adsorption using Raw-PFL were similar to the removal of malachite green using humic acid-modified magnetite and reactive black 5 removal using NaOH-treated Aspergillus flavus biomass . The thermodynamic properties of AB113 dye adsorption using Raw-PFL, however, are in good agreement with a previous study on malachite green adsorption using seed peel waste of Lupinus albus .…”

“…Studies of adsorption kinetics in aqueous effluent treatment can provide valuable insights into the adsorption mechanisms . In this study, kinetic models, namely, P-F-O, P-S-O, Elovich, and I-P diffusion, were considered to examine AB113 and MB dye adsorption onto Raw-PFL and NaOH-PFL.…”

“…Studies of adsorption kinetics in aqueous effluent treatment can provide valuable insights into the adsorption mechanisms. 87 In this study, kinetic models, namely, P-F-O, P-S-O, Elovich, and I-P diffusion, were considered to examine AB113 and MB dye adsorption onto Raw-PFL and NaOH-PFL. The gradient and intercept of the plots were used to compute the parameters for each kinetic model (Supporting Information File Figures S1, S3, S5, and S7), and the findings were compiled in Table S4.…”

Synthesis and Characterization of CuO Nanoparticles and CuO/PVA-PVP Nanocomposites: Adsorption Activity for Malachite Green (MG) Dye and Antibacterial Property in Wastewater Treatment

“…8 it was found that the nanoparticle removal efficiency increases with increasing the pH value; the highest removal efficiency of the dye was at pH 10 for both nanoparticles. The percentage of removal efficiency is comparatively less in the acidic range of pH [39]. Increasing pH leads to formation of negative charge on the adsorbent surface whereas at low pH the presence of excess H + ions, the surface of these nanoparticles was positively charged.…”

pH-responsive hollow core zeolitic-imidazolate framework-8 as an effective drug carrier of 5-fluorouracil

“…The rising value of Q e along with temperature exhibiting the endothermic process can be also affected by the pore size enlargement, surface activation, or the emergence of new active sites [37]. Meanwhile, the Q e value is observed to be lower at 50 C, which might be caused by the aggregation of adsorbents in the adsorption system which blocks the active sites of the adsorbent [38].…”
