3. Subbaiah Muthu Prabhu, Shunsuke Imamura, Keiko Sasaki*, Mono-, di- and tri-carboxylic acid facilitated lanthanum-based organic frameworks: Insights into the structural stability and mechanistic approach for superior adsorption of arsenate from water, ACS Sustainable Chemistry and Engineering, in press, 2018.12, In this study, we synthesized three metal organic frameworks (MOFs) of La, with benzoic acid (BA), 1,4-benzene dicarboxylic acid (BDC) and 1,3,5-benzenetricarboxylic acid (BTC), abbreviated as La-BA, La-BDC and La-BTC, respectively. Interestingly, the BA ligand approached La metal to form lanthanum methanoate (La(HCOO)3 instead of the La-BA MOF through an acid catalyst amide-hydrolysis mechanism, whereas La-BDC and La-BTC act as MOFs, confirmed by PXRD patterns. The mechanism of MOF formation was revealed through PXRD, FT-IR, XPS and ICP-OES analyses. This is the first report to investigate AsO43- adsorption and the dissolution behavior of La-BA, La-BDC and La-BTC in detail using different spectroscopic methods. The maximum adsorption capacities of AsO43- obtained from the Langmuir isotherm model were found to be 2.623, 3.891 and 0.280 mmol/g for La-BA, La-BDC and La-BTC, respectively, where the the dose ratio of 1 g/L with the speed of 100 rpm at room temperature. The value for La-BDC was significantly superior to the previously reported adsorbents for AsO43- to date. The presence of AsO43- on both La-BA and La-BDC was confirmed by FTIR and XPS As 3d. The PXRD patterns confirmed the formation of LaAsO4 by the precipitation mechanism after adsorption of 2.4 mM AsO43- on both La-BA and La-BDC. Sorption kinetic data of AsO43- followed a pseudo-second-order model, which is consistent with chemisorption involving the possible coordination of AsO43- on La-BA and La-BDC. These results suggested that the MOF materials can be developed for the immobilization of AsO43- from waste water..
