Ultrasound-enhanced Copper Removal by Hydrous Iron Oxide Adsorption
نویسنده
چکیده
A model system to investigate ultrasound-enhanced removal of metallic ions from aqueous solution by hydrous ferric oxide (HFO) adsorption has been conducted. The experimental data indicate that ultrasonic treatment of pre-formed HFO flocs can lead to enhanced removal of metallic ions from aqueous solution and that the level of enhancement is strongly correlated with the solution pH. Ultrasonic treatment has been shown to be effective at lowering the final solution concentration of copper species in the pH range 7.5-9.5 at copper to iron molar concentration ratios of 10 and 30%.

Effects of addition of cationic ligands in hydrous bismuth oxide on removal of fluoride from aqueous solutions
Hydrous bismuth oxides (HBO2) have been reported to have anionic sorptive properties. In the present study, removal of fluoride from aqueous solution has been explored for its possible application in drinking water treatment. The performance of fluoride removal from aqueous solutions has been studied by adding four cationic ligands (Fe, Mg, Ca and Cu) in the matrix of hydrous bismuth oxide (HBO...
متن کاملRole of Surface Precipitation in Copper Sorption by the Hydrous Oxides of Iron and Aluminum.
Isotherms were developed at pH 6.9 for adsorption (ADS) and coprecipitation (CPT) of Cu by hydrous oxides of Fe (HFO) and Al (HAO) to study the role of sorbate/sorbent ratio in metal cation removal. For low sorbate/sorbent conditions, HFO had a higher Cu retention capacity than HAO regardless of contact methodology. For either oxide, CPT was consistently more effective than ADS in removing Cu f...

The removal of copper (II) ion by using ultrasound pre-treatment to increase the pores structure and surface area on peanut husk powder via direct sonication (ultrasound probe) and indirect ultrasound (ultrasound bath) at powder level 3.5 W. In previous studies, researchers had applied ultrasound simultaneous with adsorption process. This method is not suitable to treat huge amount of heavy met...
متن کاملRemoval of tetracycline from water by Fe-Mn binary oxide.
Significant concerns have been raised over the presence of antibiotics including tetracyclines in aquatic environments. A series of Fe-Mn binary oxide with different Fe:Mn molar ratios was synthesized by a simultaneous oxidation and coprecipitation process for TC removal. Results showed that Fe-Mn binary oxide had higher removal efficiency than that of hydrous iron oxide and hydrous manganese o...
متن کاملFast removal and recovery of congo red by modified iron oxide magnetic nanoparticles
The adsorption and removal of congo red from an aqueous solution by iron oxide nanoparticles (IONPs) coated with cetyltrimethylammonium bromide (CTAB) as adsorbent was reported. The novel magnetic separation was quite efficient for the adsorption and desorption of congo red. The effect of temperature, pH of aqueous medium, and interfering ions on the recovery process were also investigated. The...
