Covalent Triazine Polymer–Fe3O4 Nanocomposite for Strontium Ion Removal from Seawater
Industrial & Engineering Chemistry Research, 2017Co-Authors: Arunkumar Rengaraj, Yuvaraj Haldorai, Pillaiyar Puthiaraj, Seung Kyu Hwang, Taegong Ryu, Junho Shin, Young-kyu Han, Wha-seung Ahn, Yun Suk HuhAbstract:A microporous covalent triazine polymer (CTP) is synthesized via a Friedel–Crafts reactIon and used as a solid support to immobilize magnetite Fe3O4 nanoparticles. Thermogravimetric analysis shows that approximately 60 wt % Fe3O4 is loaded onto the composite, and transmissIon electron microscopy analysis illustrates that the Fe3O4 nanoparticles are uniformly impregnated into the CTP surface. The CTP–Fe3O4 nanocomposite is an efficient adsorbent for the removal of Strontium Ion (Sr2+) from seawater. Response surface methodology, employed to optimize the removal of Sr2+, confirms that the optimal conditIons for this removal are 0.55 mg, pH 7, 40 °C, and 250 min. The experimental results illustrate that the adsorptIon process fits well with the Freundlich isotherm, with a correlatIon coefficient of 0.976 and a maximum adsorptIon capacity of 128 mg g–1. The kinetic study demonstrates that the adsorptIon behavior follows pseudo-second-order kinetics. The adsorbent is easily recovered from seawater using an ext...

Strontium Ion sr2 separatIon from seawater by hydrothermally structured titanate nanotubes removal vs recovery
Chemical Engineering Journal, 2016Co-Authors: Jungho Ryu, Taegong Ryu, Jum Suk Jang, Soonhyun Kim, Hyejin Hong, Jeongsik Hong, Minsun Kim, Insu Park, Kangsup Chung, Byoung-gyu KimAbstract:•Titanate nanotubes (TiNTs) were synthesized by a simple hydrothermal reactIon.•The sorptIon of Strontium (Sr) on TiNTs rapidly occurred, achieving Sr uptake 97mg/g.•Na had little effect on Sr sorptIon despite the sorptIon mechanism of the Na exchange.•Ca significantly hindered Sr sorptIon on TiNTs among co-existing catIons in seawater.•TiNTs could be easily regenerated by acid treatment and reused for repeated cycles.
