An optimization study for the sol-gel synthesis of Ni0.5Zn0.5Fe2O4 nanoparticles and their performance adsorptive removal methylene blue (MB) dye was reported. The as-produced samples associated calcined corresponding ones in range 400–800 °C were systematically characterized structure microstructure using different techniques. For expected best candidate MB removal, pure NiZn nanoferrite (optimized parameters: Fuel=Urea; pH=5; [Fe3+]:0.025 M; Total nitrate to fuel molar ratio=8/6.66)...

Abstract Phenolic compounds can be found in industrial or agricultural waste, such as waste water from olive mills. Because of the environmental problem caused by this residue oil production, aim work was to model effect salts on solubility four phenolic compounds. For purpose, solubilities gallic acid, protocatechuic vanillic acid and vanillin have been measured various chloride solutions at constant temperature. The Clegg–Simonson–Pitzer activity coefficient, together with dissociation...

The solid–liquid equilibrium of vanillic acid (3) in solvent mixtures 1-propanol (1) + water (2) and 2-propanol was estimated utilizing gravimetric method findings the temperature range 283.15–323.15 K. solvency depends on dissolvable mixtures, it determined through van't Hoff–Jouyban–Acree Apelblat–Jouyban–Acree models. Normal relative deviations lower than 3% root-mean-square 0.53 × 10–3 were obtained for reciprocal examinations. With solubility data this study results from our previous...

The solubility of 2-cyanoacetamide (2-CA) was ascertained by means a gravimetric technique in four different kinds aqueous mixed solvents, specifically water + (methanol (MeOH), ethanol (EtOH), 1-propanol (1-PrOH), or 2-propanol (2-PrOH)). experiment conducted between 283.15 and 323.15 K temperature. findings show that all binary solvent systems, 2-CA becomes more soluble at higher temperatures. KAT-LSER model employed to analyze the impact solute–solvent intermolecular interactions on...

Benzohydrazide (BH) and 2-hydroxybenzohydrazide (HBH) have gained attention due to their diverse characteristics wide applications in pharmacy organic synthesis. In this study, a gravimetric technique was used measure the ability of BH HBH dissolve six monosolvents [water, methanol (MeOH), ethanol (EtOH), propan-1-ol (1-PrOH), propan-2-ol (2-PrOH), butan-1-ol (1-BuOH)] at an atmospheric pressure 0.1 MPa.

The present investigation used the inverse Kirkwood-Buff integrals technique to determine best solvation parameters for DIF in two distinct alcoholic aqueous solutions, spanning a temperature range from 293.15 K 323.15 K. analysis demonstrated that values of displayed nonlinear trend concerning composition co-solvent. ( ) various solutions revealed variations were contingent upon concentration Notably, positive recorded mixtures with all compositions methanol and 0.00 < x1 0.33-0.35 0.50...

The solubility of gallic acid, vanillin, syringic and protocatechuic acid in aqueous solutions various concentrations sodium sulfate was determined from (293.15 to 318.15) K at atmospheric pressure using a thermostatted reactor HPLC analysis. Results showed salting-out effect on the tested phenolic compounds. data were accurately correlated semiempirical equation. temperature dependence used estimate thermodynamic properties such as Gibbs free energy (ΔsolGo), molar enthalpy dissolution...

The partition coefficient, KOW, of some phenolic compounds, PhC, between water and 1-octanol, was determined at six temperatures from (293.15 to 318.15) K using a slow-stirring method. log KOW values protocatechuic acid, vanillic vanillin range (0.78 0.61), (1.46 1.18), (1.25 0.99), respectively, over the temperature studied. Obtained 298.15 agree well with literature data. van't Hoff plots versus T−1 exhibit linearity increasing by 13 % 21 this range. On basis fluid phase equilibrium...

In this work, the solubility data of syringic acid (SA) in eight mono solvents, including methanol, ethanol, 2-propanol, 1-butanol, 2-butanol, 1-hexanol, ethylene glycol, and ethyl acetate, water + methanol mixtures were obtained experimentally temperatures ranging from 283.15 to 323.15 K at 5 intervals with a gravimetric method under pressure 0.1 MPa. It is found that SA increases increasing temperature all selected pure binary mixed solvents within range studied. The mole fraction be...

This study examines the solubility of benzamide (BZA), correlating with theoretical models and calculating thermodynamic property parameters. In this work, gravimetric method was utilized to determine in three individual solvents (methanol, ethanol, 1-propanol, ethyl acetate), as well (ethanol + acetate) (methanol (1-propanol binary mixed solvents. The results demonstrated that increased first then decreased increasing mole fractions methanol/ethyl acetate ethanol/ethyl at same temperature....

Using a thermostated reactor and UV/vis spectrophotometer analysis, the solubility of protocatechuic acid (PA) in ethanol, methanol, methyl acetate, ethyl acetate was measured from (293.15 to 318.15) K at atmospheric pressure.
