| Summary: | The current work reports the physico-chemical properties of MgAl layered double hydroxide (LDH), which was synthesized via alkali free co-precipitation method with ratio of 4:1 and further calcined at 450 ºC for 13 h. The correlation of crystallinity, morphology and particle size of MgAl LDH before and after calcined were examined using thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), Brunaeur-Emmette-Teller (BET), Fourier transform infrared (FTIR) and field emission scanning electron microscope (FESEM). The conductivity study of calcined MgAl LDH was measured using an AC conductivity meter, which reveals the optimum concentration of MgAl LDH with an electrolytic conductivity (κ) of 0.1256 µS/cm at 25 ºC. This concentration was further used in the remaining electrolyte system in the presence of lithium perchlorate (LiClO4). The κ values was measured at various Csalt (10–8–10–3 mol cm–3) and the limiting molar conductivity (Λo) values was also determined using power law. © 2024 Asian Publication Corporation.
