a novel, simple, sensitive and effective method has been developed for preconcentration of hg(ii) on nano-fe3o4-dop-ed solid-phase extraction adsorbent. in this paper, dioctyl phthalate (dop) was used to encapsulate nano-fe3o4 and produce a nano-fe3o4-dop sorbent based new sorbent was prepared. this was treated with ethylenediamine (ed) in another solvent-free procedure for the formation of a n...
Introduction: Volatile organic compounds from industrial activities are one of the most important pollutants released into the air and have adverse effects on human and environment. Therefore, they should be removed before releasing into atmosphere. The aim of the study was to evaluate xylene removal from air by nano-grapheme and nano-graphene oxide in comparison with activated carbon adsorbent...
This research has studied equilibrium adsorption isotherms of Ketotifen on carbon nanotube. And also results of experiments through Freundlich,Temkin and Langmuir models have been studied and it has found different parameters of these models for carbon nano-tube adsorbent. According to the error rate for each model, we obtained a good agreement between these data which it showed the best agreem...
The present study seeks to investigate the capacity of polyaniline/titanium dioxide (PAn/TiO2) and Polypyrrole/titanium dioxide (PPy/TiO2) nano-adsorbents to adsorb Congo red anionic dye (CR) from aqueous solution. The variables effective in CR adsorption, including adsorbent dose, pH of the solution, contact time, initial dye concentration, and temperature were examined. The study yielded the ...
Background: Antibiotics and their metabolites are known as dangerous non-degradable substances that potentially remain after the wastewater treatment process. Therefore, it is necessary to remove these compounds from aqueous solutions. This study aimed to use layered double nano-hydroxides to remove carbamazepine, cephalexin, and ciprofloxacin. Methods: In this experimental study the charact...
BACKGROUND Nowadays significant attention is to nanocomposite compounds in water cleaning. In this article the synthesis and characterization of conductive polyaniline/clay (PANI/clay) as a hybrid nanocomposite with extended chain conformation and its application for water purification are presented. METHODS Clay samples were obtained from the central plain of Abhar region, Abhar, Zanjan Prov...
The present work describes the synthesis of copper oxide nanoparticles (CuONPs) via a solution process with the aim of applying the nano-adsorbent for the reduction of methylene blue (MB) dye in alkaline media. These NPs were characterized via Field emission scanning electron microscopy (FE-SEM), X-ray diffraction, high-resolution Transmission electron microscopy (TEM), and ultra violet UV-visi...
In the current investigation a novel nano hybrid adsorbent MCM-41/N-(3-trimethoxysilyl)-propyl)diethylenetriamine (MCM-41/TMSPDETA) was prepared and was characterized using DLS (Dynamic Light Scattering), Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analytical techniques and Transmission electron microscopy (TEM). The synthesized MCM-41/TMSPDETA adsor...
Today, sulfur removal from fuels has improved by new adsorbents such as zeolites that needs extensive studies. This study investigates the feasibility of sulfur compounds adsorption on improved nano zeolite existing in organic fuels and desorption of them from nano-adsorbent.Some properties of improved nano zeolite were analyzed to receive better sulfur compounds adsorption.<e...
