Ramesh Chitrakar, Auteur ; Satoko Tezuka, Auteur ; Akinari Sonoda, Auteur |We synthesized crystalline akaganéite (β-FeOOH; Cl− type) by hydrolysis of FeCl3 solution at 100 °C and examined the ion-exchange properties with BrO3−. The uptake rate of BrO3− was so fast that equilibrium was attained in 60 min. The uptake was[...]

Calcined Mg–al layered double hydroxides for uptake of trace levels of bromate from aqueous solution
Ramesh Chitrakar, Auteur ; Akinari Sonoda, Auteur ; Yoji Makita, Auteur |Layered double hydroxides of Mg and Al (Mg-Al LDH) were synthesized with OH-, Cl-, or CO32- as charge compensating anions. The materials were calcined at 500 °C in air. The bromate uptakes of calcined and uncalcined LDH materials were investigat[...]

Ramesh Chitrakar, Auteur ; Satoko Tezuka, Auteur ; Akinari Sonoda, Auteur ; Kohji Sakane, Auteur |We report a very simple and efficient method to prepare LDHs of Mg−Al, Mg−Fe, and Zn−Al by simply mixing solid divalent metal oxide with trivalent metal chloride solution at 30 °C. Calcined Mg−Al and Mg−Fe are effective in removing low concentra[...]

Ramesh Chitrakar, Auteur ; Keisuke Mizobuchi, Auteur ; Akinari Sonoda, Auteur |Batch experiments were performed to examine the BrO3− uptake from dilute aqueous solutions on amorphous aluminum hydroxide (Cl− type), which was synthesized by addition of a 3 mol/dm3 NaOH solution to a 0.1 mol/dm3 AlCl3 solution until the pH re[...]
