Removal of boron, fluoride and nitrate by electrodialysis in the presence of organic matter
نویسندگان
چکیده
14 The removal of the trace inorganic contaminants boron (B(OH)4 ), fluoride (F ) and nitrate (NO3 ) 15 from synthetic aqueous solutions containing organic matter using electrodialysis was investigated. 16 The transport of the contaminants through the ion-exchange membranes was evaluated in relation 17 to hydrated ionic radius, whereby a positive correlation was found in absence of organic matter. 18 NO3 , with the smaller hydrated ionic radius and weaker hydration shell, was removed more 19 effectively than F, which has a larger hydrated ionic radius and stronger hydration shell. The 20 removal of F and NO3 was not significantly influenced by solution pH due to their pH independent 21

متن کاملEffect of Co-existing Heavy Metals and Natural Organic Matter on Sorption/Desorption of Polycyclic Aromatic Hydrocarbons in Soil: A Review
Polycyclic aromatic hydrocarbons (PAHs), abundant in mixed contaminant sites, often coexist with heavy metals. The fate and remediation of PAHs depend heavily on the sorption and desorption behavior of these contaminants. The sorption behavior can in turn be highly affected by certain soil components and properties, such as soil organic matter (SOM) and the presence of heavy metals. Through rev...
