Strontium uptake using Titanate nanotubes as adsorbent material prepared via hydrothermal method |
| 초록 |
Strontium ions sorption recovery from seawater is a most challenging task. Seawater is the rich resource of most of the salts dissolved in ionic form. Strontium ions concentration in seawater has approximately ~8 ppm which is very poor from other alkali and alkaline earth metals ion concentrations. This ions uptake recovery experiment has been based on strontium ions sorption in its aqueous salt as well as calcium aqueous mixtures (~ 400 ppm Ca) solution. During this experiment titanate metal oxide nanotubes used as adsorbent material for aqueous strontium ions sorption. Ion adsorption mechanism of strontium recovery has been studied and our experimental results has shown the titanate nanotubes were the best promising adsorbent material for strontium uptakes because of large surfaced area and high pore volume which adsorbed almost 99% of strontium ions from strontium chloride aqueous salt mixture. Titanate nanotubes were synthesized from molten salts TiO2 nanowires by using one pot hydrothermal method at high alkaline solution (10M NaOH). Titanate nanotubes material characterizations have been studied by FE-SEM, XRD, BET and strontium recovery analysis has been performed by inductive coupled plasma instrument |
