Hydroxyapatite (HAp) is a versatile material with wide-ranging applications, including its utility as an adsorbent. However, brittleness and limited adsorption capacity pose challenges, prompting the incorporation of chitosan (CTS) fillers to enhance mechanical strength properties. The hydroxyapatite/chitosan (HAp/CTS) composite was synthesized via in-situ method, utilizing natural sources such calcium ions from cuttlefish bones extracted shrimp shells. Various concentrations (10, 20, 30, 40, 50 wt%) were explored in synthesis process, optimal Rhodamine B dye observed at 30% concentration, yielding 0.1832 mg/g. Validation HAp/CTS achieved through X-ray diffraction, revealing presence CTS new peak 2θ 19.23°, while infrared spectroscopy confirmed absorption bands for both HAp CTS. Additionally, scanning electron microscopy-energy dipersive (SEM-EDS) investigations revealed irregular shapes agglomeration, resulting Ca/P ratio 1.80 composite. HAp/CTS-30% demonstrated efficient following Freundlich isotherm equation, pseudo-second-order kinetics, exhibited good reusability. These findings suggest that could serve promising, cost-effective solution treating industrial wastewater.

Measuring the effects of liquid bulk viscosity numerically on a spherical nitrogen bubble in aqueous H2SO4

AIP Advances, Год журнала: 2025, Номер 15(4)

Опубликована: Апрель 1, 2025

The current study extensively simulates multiple theories concerning the mechanism of bubble formation during interaction between an aqueous H2SO4 solution and nitrogen gas. This leads to pressure surges high internal temperatures due violent collapse inertial bubble. examines effects liquid volume viscosity on dynamics a single cavitation by applying Gilmore model interface under various boundary conditions, such as volume, N2, surface tension, temperature, pressure, etc. An in bubbles was used this investigation. A comprehensive frequency, asymptotic growth, growth carried out. To quantitatively investigate influence fluid shear bubble, several numerical calculations were performed at viscosities ranging from 0.002 0.014 Pa s, both with without viscosity. In addition, focuses maximum stress rather than highest temperature. Wherever possible, experimental validations that serve guide for theoretical predictions are also provided. findings indicate while impact boom may be negligible lower viscosities, it cannot completely ignored relatively viscosities. analysis offers insight into how thermodynamic method modifies intensity advances our understanding complex thermal-hydrodynamic phenomenon.

Adsorption-based removal is a highly efficient environmental phenomenon employed to eliminate various dyes, such as crystal violet (CV), which prevalently used in the textile industry and subsequently discharged into natural ecosystems. This study aims utilize bentonite clay sourced from Algeria for extraction of cationic dye (CV) wastewater. The characterization was conducted using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD). Evaluations assessed impact parameters including pH, stirring time, temperature, initial concentration on adsorption efficiency. Optimal conditions maximal CV were determined be 430.18 mg g-1 at an adsorbent-to-dye solution ratio 1 g L-1, pH 11.06, equilibrium time 40 minutes, temperature 40°C. kinetics best described by pseudo-second-order model, while Freundlich isotherm model aptly isotherms. Thermodynamic underscored spontaneous exothermic nature process raw bentonite. research provides novel insights effective water wastewater Algerian clay.
