Through various analyses, the chemical formula of the proposed Mg/Fe-LDH was determined to be [Mg(0.76)Fe(0.24)(OH)(2)](Cl(-))(0.21)(CO(3)(2-))(0.02)·0.76H(2)O. Furthermore, amorphous Fe(III) impurities were contained in the present Mg/Fe-LDH. The proposed Mg/Fe-LDH exhibited clear selectivity for nitrate ions dissolved in water. This selectivity for nitrate ions can be explained by an anion-sieve effect by the existence of amorphous Fe(III) impurities. Our findings suggest that it is possible to synthesize LDHs with high selectivity for various anions by effective hybridizing Fe(III) impurities."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420282801188171776","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"60314051"},{"@type":"NRID","@value":"1000060314051"},{"@type":"NRID","@value":"9000017046039"},{"@type":"NRID","@value":"9000006900288"},{"@type":"NRID","@value":"9000331909511"},{"@type":"NRID","@value":"9000331080879"},{"@type":"NRID","@value":"9000312841506"},{"@type":"NRID","@value":"9000391844684"},{"@type":"NRID","@value":"9000391843438"},{"@type":"NRID","@value":"9000255702062"},{"@type":"NRID","@value":"9000258461236"},{"@type":"NRID","@value":"9000000126683"},{"@type":"NRID","@value":"9000006639302"},{"@type":"NRID","@value":"9000006072697"},{"@type":"NRID","@value":"9000391833858"},{"@type":"NRID","@value":"9000391833852"},{"@type":"NRID","@value":"9000391831271"},{"@type":"NRID","@value":"9000391832927"},{"@type":"NRID","@value":"9000398815963"},{"@type":"NRID","@value":"9000257722475"},{"@type":"NRID","@value":"9000010342016"},{"@type":"NRID","@value":"9000018659678"},{"@type":"NRID","@value":"9000002741310"},{"@type":"NRID","@value":"9000391891805"},{"@type":"NRID","@value":"9000391852397"},{"@type":"NRID","@value":"9000391844741"},{"@type":"NRID","@value":"9000391831757"},{"@type":"NRID","@value":"9000391830528"},{"@type":"NRID","@value":"9000391832990"},{"@type":"NRID","@value":"9000391840628"},{"@type":"NRID","@value":"9000391847204"},{"@type":"NRID","@value":"9000018152563"},{"@type":"NRID","@value":"9000312840564"},{"@type":"NRID","@value":"9000243732038"},{"@type":"NRID","@value":"9000391891217"},{"@type":"NRID","@value":"9000391866240"},{"@type":"NRID","@value":"9000256019766"},{"@type":"NRID","@value":"9000327088468"},{"@type":"NRID","@value":"9000273394673"},{"@type":"NRID","@value":"9000018526107"},{"@type":"NRID","@value":"9000302770198"},{"@type":"NRID","@value":"9000391853053"},{"@type":"NRID","@value":"9000391832584"},{"@type":"NRID","@value":"9000391843950"},{"@type":"NRID","@value":"9000398796796"},{"@type":"NRID","@value":"9000405705135"},{"@type":"NRID","@value":"9000005478521"},{"@type":"NRID","@value":"9000018507599"},{"@type":"NRID","@value":"9000239567560"},{"@type":"NRID","@value":"9000391835129"},{"@type":"NRID","@value":"9000391840276"},{"@type":"NRID","@value":"9000263043609"},{"@type":"NRID","@value":"9000367403179"},{"@type":"NRID","@value":"9000022209108"},{"@type":"NRID","@value":"9000391866530"},{"@type":"NRID","@value":"9000391836047"},{"@type":"NRID","@value":"9000396140072"},{"@type":"NRID","@value":"9000409335144"},{"@type":"NRID","@value":"9000414344809"},{"@type":"NRID","@value":"9000314388443"},{"@type":"NRID","@value":"9000391887175"},{"@type":"NRID","@value":"9000391884844"},{"@type":"NRID","@value":"9000391831799"},{"@type":"NRID","@value":"9000340942688"},{"@type":"NRID","@value":"9000242665186"},{"@type":"NRID","@value":"9000243748536"},{"@type":"NRID","@value":"9000243732157"},{"@type":"NRID","@value":"9000240180660"},{"@type":"NRID","@value":"9000241168847"},{"@type":"NRID","@value":"9000391885648"},{"@type":"NRID","@value":"9000391891161"},{"@type":"NRID","@value":"9000391874205"},{"@type":"NRID","@value":"9000391836145"},{"@type":"NRID","@value":"9000391840359"},{"@type":"NRID","@value":"9000391844940"},{"@type":"NRID","@value":"9000364985800"},{"@type":"NRID","@value":"9000364986298"},{"@type":"NRID","@value":"9000391892623"},{"@type":"NRID","@value":"9000414827013"},{"@type":"NRID","@value":"9000392009266"},{"@type":"NRID","@value":"9000398796477"},{"@type":"NRID","@value":"9000409335129"},{"@type":"NRID","@value":"9000002021157"},{"@type":"NRID","@value":"9000020459194"},{"@type":"NRID","@value":"9000391887171"},{"@type":"NRID","@value":"9000391891273"},{"@type":"NRID","@value":"9000391831537"},{"@type":"NRID","@value":"9000391831552"},{"@type":"NRID","@value":"9000392009539"},{"@type":"NRID","@value":"9000257724647"},{"@type":"NRID","@value":"9000241735029"},{"@type":"NRID","@value":"9000242255157"},{"@type":"NRID","@value":"9000014271369"},{"@type":"NRID","@value":"9000370746457"},{"@type":"NRID","@value":"9000391862488"},{"@type":"NRID","@value":"9000391870870"},{"@type":"NRID","@value":"9000391846939"},{"@type":"NRID","@value":"9000391832201"},{"@type":"NRID","@value":"9000391840280"},{"@type":"NRID","@value":"9000391840072"},{"@type":"NRID","@value":"9000396160760"},{"@type":"NRID","@value":"9000411391968"},{"@type":"NRID","@value":"9000265565239"},{"@type":"NRID","@value":"9000391862629"},{"@type":"NRID","@value":"9000391870500"},{"@type":"NRID","@value":"9000391830728"},{"@type":"NRID","@value":"9000391830485"},{"@type":"NRID","@value":"9000391844830"},{"@type":"NRID","@value":"9000345352750"},{"@type":"NRID","@value":"9000333078513"},{"@type":"NRID","@value":"9000259336390"},{"@type":"NRID","@value":"9000391880608"},{"@type":"NRID","@value":"9000391861804"},{"@type":"NRID","@value":"9000391843435"},{"@type":"NRID","@value":"9000399345403"},{"@type":"NRID","@value":"90002560288
