Application of Granular Ferric Hydroxide in Removal of Nitrate from Aqueous Solutions
The aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (GFH). The effect of factors such as initial concentration of nitrate, pH, contact time, and adsorbent mass were determined. The study was done in laboratory–scale in which synthetic nitrate solutions in a batch reactor were placed in contact with the adsorbent to model adsorption kinetics. It was found ...

متن کاملnitrate removal from water using granules ferric hydroxide absorbent
background: one of the major sources of drinking water contamination is nitrate. nitrate concentrations of more than the standard levels (45mgl -1 based on nitrate) could cause methemoglobinemia in children. the aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (gfh). also in this study, the effect of factors such as initial concentration of nitrate, contac...
متن کاملNitrate Removal from Aqueous Solutions Using Granular Activated Carbon Modified with Iron Nanoparticles (RESEARCH NOTE)
Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...
متن کاملKinetics and Thermodynamic Study of Nitrate Adsorption on Granular Ferric Hydroxide
This study explored the feasibility of using granular ferric hydroxide as adsorbent for the removal of NO3-N. Optimum conditions for NO3-N removal were found to be pH 5.0 and equilibrium time 80min. The equilibrium sorption isotherm was better described by Langmuir sorption isotherm model. The maximum sorption capacity of granular ferric hydroxide was 4.254mg/g at 298K. A comparison of four kin...
