in this study, a new adsorbent, silver nanoparticle loaded on activated carbon (ag˗np˗ac) was used for removal of acid yellow199 (ay 199) dye. this novel material was characterized and identified by different techniques such as brunauer, emmett and teller (bet), field emission scanning electron microscopy (fesem), x-ray diffraction (xrd) analysis. unique properties of this adsorbent such as hig...
In this work, the antimicrobial property of nanocomposite prepared by loading of silver nanoparticle onto activated carbon (AgNP-AC) was studied. The silver nanoparticles were synthesized biologically from the culture Enterobacter aerogenes and loaded onto the activated carbon. The nanoparticle and nanocomposite were characterized by UV-vis, scanning electron microscopy and X-ray diffraction st...
this study focus on the preparation of two supports including activated carbon derived from medlar and palladium nanoparticles loaded on activated carbon (pd-np-ac). subsequently, both adsorbent modified with a novel schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. the method is based on c...
the objective of this study was to assess the potential of cadmium sulfide nanoparticles loaded onto activated carbon (cdsn-ac) for the removal of sunset yellow (sy) dye from aqueous solution. adsorption studies were conducted in a batch mode varying solution ph, contact time, initial dye concentration, cdsn-ac dose. in order to investigate the efficiency of sy adsorption on cdsn-ac, pseudo-fir...
Approximately 10-20% of the total dyes in the world is consumed in the textile industry. The present study aimed to investigate the photocatalytic activity of zinc oxide nanoparticles (ZnO) immobilized on synthetic activated carbon in the removal of the acid blue 113 dye from aqueous solutions. This experimental study was conducted in a photo-reactor with the useful volume of one liter. The eff...
In this study, the electrospinning method was used to prepare silver nanoparticle–activated carbon (AgNP-AC) composite nanofiber membranes, aiming obtain a high-performance dual-functional filter fiber membrane with good antibacterial and adsorption properties. A scanning electron microscope (SEM), X-ray diffractometer (XRD), other instruments were characterize morphology structure of nanofiber...
The use of nebulizable, nanoparticle-based antimicrobial delivery systems can improve efficacy and reduce toxicity for treatment of multi-drug-resistant bacteria in the chronically infected lungs of cystic fibrosis patients. Nanoparticle vehicles are particularly useful for applying broad-spectrum silver-based antimicrobials, for instance, to improve the residence time of small-molecule silver ...
background and purpose: recently, release of pollutants such as pharmaceuticals to the environment becomes one of the most important problems for soil and water. the present study was conducted to introduce walnut shell-based activated carbon (ac) as a new low-cost adsorbent for the removal of cephalexin (cfx) antibiotic from aqueous solutions. materials and methods: this study was conducted in...
