FLUOROQUINOLONES ANTIBIOTICS ADSORPTION ONTO POLYMER COATED MAGNETIC NANOPARTICULAR ACTIVATED CARBON
Abstract Background and purpose: Phenols are considered as priority pollutants because of their potential harm to human health. So, they should be removed from water resources to avoid further pollutions. The aim of this research was to evaluate phenol adsorption from aqueous solution using activated carbon provided from Populus alba. Materials and methods: In this experimental study we use...
Parachlorophenol has an extended usage in refineries, petrochemical industries, insecticide, and herbicide manufacturing industries. Tire a solid waste, which is disposed in large amounts each year, a large number of them in landfills can cause irreparable environmental impacts. Consequently lots of efforts were done to produce activated carbon from used tires. Activated carbon was made in labo...
In this study, powder activated carbon (PAC) and magnetic nanoparticles of iron (III) oxide were used for synthesis of Fe3O4-activated carbon magnetic nanoparticles (AC-Fe3O4 MNPs) as an adsorbent for the removal of aniline. The characteristics of adsorbent were evaluated by SEM, TEM, XRD and BET. Also, the impact of different parameters such as pH, contact time, adsorbent dosage, aniline initi...
Introduction: Hexavalent chromium (VI) is a very strong oxidizing agent that, despite its many uses in various industries, duration of the exposure can lead to lung cancer, deep wounds (in the hands, arm, tongue and palate), nasal septum perforation, burning and inflammation in the nose, lung and upper respiratory tract, asthma, contact dermatitis, damage to the kidneys and liver, and skin alle...
background: nanotechnology is a new approach that has been lionized in recent years. one of its applications is its consumption as an absorbent. in this study, the single-wall carbon nanotubes (swcnts) were used as an absorbent for sampling benzene in the air. materials and methods: for this study, swcnts manufactured by iran and skc’s activated charcoal were used for sampling benzene vapors. p...
dissolved organic nitrogen (don) can react with disinfectants to produce numerous disinfectionbyproducts (dbps), particularly nitrogen-containing dbps (n-dbps), and produce serious adverse effectson public health. widely used biological processes in drinking water treatment can increase don in effluents,and enhance these ill effects. this study investigated don in a full-scale two-stage ozonati...
