Adsorptive Removal and Adsorption Kinetics of Fluoroquinolone by Nano-Hydroxyapatite

Adsorptive Removal of Fluoroquinolone Antibiotics Using Bamboo Biochar

The occurrence of fluoroquinolone antibiotics in wastewater has drawn great attention. Adsorption of widely used fluoroquinolone antibiotics (enrofloxacin and ofloxacin) in wastewater using bamboo biochar was investigated. More than 99% of fluoroquinolone antibiotics were removed from the synthetic wastewater through adsorption. Adsorption capacities of bamboo biochar slightly changed when pH i...

Kinetics and thermodynamics of cadmium ion removal by adsorption onto nano zerovalent iron particles.

Nano zerovalent iron (nZVI) is an effective adsorbent for removing various organic and inorganic contaminants. In this study, nZVI particles were used to investigate the removal of Cd(2+) in the concentration range of 25-450 mg L(-1). The effect of temperature on kinetics and equilibrium of cadmium sorption on nZVI particles was thoroughly examined. Consistent with an endothermic reaction, an i...

Removal of Bisphenol-A by NaP Zeolite/Hydroxyapatite Composite: Adsorption Experiments and Modeling by Artificial Neural Networks

In this paper, we have reported removal of Bisphenol A (BPA) by Hydroxyapatite/NaP zeolite (HAp: Zeolite ) nanocomposite which synthesized in previous our work and characterized by using different methods such as X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, Energy Dispersive X-ray analysis, surface area, and thermogravimetric analysis. To investigate...

Adsorption Isotherm and Kinetics Study: Removal of Phenol Using Adsorption onto Modified Pistacia mutica shells

Background and purpose: Phenol is an aromatic hydrocarbon and one of the banzan derivatives which has a higher dissolution rate in water. Therefore, it must be removed for water pollution prevention. The aim of this study was to investigate the possibility of Pistaciamuticabio mass as an alternative adsorbent for phenol removal from aqueous solution. Materials and Methods: The effect of variou...
