Preparation, characterization and adsorption potential of the NH4Cl-induced activated carbon for the removal of amoxicillin antibiotic from water

Investigating the potential of carbon activated with NH4Cl for catalyzing the degradation and mineralization of antibiotics in ozonation process

“…Ozone is the strongest primary oxidant and has a range of applications in the water and wastewater industries. Its low solubility and limited mass transfer, however, characterize it as having low mineralization efficiency for complex organic contaminants and as producing numerous intermediates that make ozonation an expensive and unattractive oxidation process (Pocostales et al, 2010;Homem et al, 2011;Moussavi et al, 2013a). Catalytic ozonation was developed to address these deficiencies.…”

“…The authors (Moussavi et al, 2013a) recently prepared and characterized a carbon that is chemically activated by NH 4 Cl (NAC) in which the density of the surface functional groups (particularly the hydroxyl group) is much greater than that of analytical-grade activated carbon (Merck). The basic groups include hydroxyl and actively contribute to generation of • OH by direct reaction of the groups with ozone (Alvárez et al, 2006).…”

“…Emerging contaminants enter the environment and natural water resources mainly through human and industrial activity. Pharmaceuticals, particularly antibiotics, are released into the water supply in effluent from pharmaceutical plants and municipal wastewater treatment plants (Moussavi et al, 2013a). They are major groups of concern of emerging contaminants that adversely affect ecological and human health.…”

Nitrate Uptake from Water by Means of Tailored Adsorbents

“…The relative intensity of such bands varies frequently when electronegative substituents are found in the aromatic rings because of their disturbing effect on the electron density distribution (Fu et al 2009). Furthermore, a strong absorption band at wave numbers from 1420 to 1100 cm −1 is observed in the FTIR spectra of PA-N, demonstrating that oxygen is functioning to stretch carboxylic groups and that carboxylate groups are present on the surface of this adsorbent material (Moussavi et al 2013). These adsorbents were also examined by FTIR spectroscopy after the nitrate adsorption experiments.…”

Influence of the amoxicillin concentration on organics removal and microbial community structure in an anaerobic EGSB reactor treating with antibiotic wastewater

“…Therefore, effective removal of AMX from the industrial wastewater is especially important. Several methods are available for this purpose, including advanced oxidation [9,10], membrane (RO-UF) filtration [11] and adsorption process [12][13][14]. However, high cost was still the serious bottleneck for these methods.…”
