نویسندگان
چکیده
Kinetics of phosphate adsorption by Ca/Cr layered double hydroxide (LDH) in a batch reactor was investigated this study. The kinetic experiments indicated that the sorption from synthetic feed solution synthesised LDH very fast, with over 98% removal being achieved within 5 min contact. Kinetic modeling process to different models (pseudo first order, pseudo second Elovich and intraparticle diffusion) showed pseudo-second order model best described process. Studies effect hydrochemistry on such as initial pH, ionic strength organic load contamination interference, nominal amount removed LDH. Overall, study chemisorption precipitation are active contributory mechanisms solution. Key words: Adsorption kinetics, chemisorption, hydroxide, removal, precipitation.

Adsorption of Arsenic on MgAl Layered Double Hydroxide
Groundwater in the Eastern Croatia, as well in the South-eastern Hungary, contains relatively high concentrations of arsenic that can cause chronic toxicity to humans. Therefore, the aim to find an effective composite adsorbent that can be applied for arsenic water remediation by introducing it in the groundwater treatment is very important. The presented results were obtained using layered dou...

متن کاملSystemic toxicity induced by aggregated layered double hydroxide nanoparticles
Layered double hydroxide (LDH) nanoparticles are emerging as one of the promising nanomaterials for biomedical applications, but their systemic toxicity in vivo has received little attention. In the present study, the effects of inorganic nanoparticle aggregation on their systemic toxicity were examined. Remarkably, aggregation was observed after the mixing of naked LDH nanoparticles with salin...
متن کاملThe Adsorption of Dextranase onto Mg/Fe-Layered Double Hydroxide: Insight into the Immobilization
We report the adsorption of dextranase on a Mg/Fe-layered double hydroxide (Mg/Fe-LDH). We focused the effects of different buffers, pH, and amino acids. The Mg/Fe-LDH was synthesized, and adsorption experiments were performed to investigate the effects. The maximum adsorption occurred in pH 7.0 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) buffer, and the maximum dextranase adsorp...
