A hydrotalcite-like compound prepared through chemical deposition using calcined dolomite as the magnesium source (D-LDH) was applied to remove borate. D-LDH calcined at different temperatures was characterized by specific surface area measurements, scanning electron microscope images, X-ray diffraction (XRD) patterns, and Fourier transform infrared (FTIR) spectra to optimize the calcination temperature and maximize the sorption capacity of borate. Greater sorption density of borate was observed at higher calcination temperature, and the sample calcined at 700 degrees C showed the maximum sorption density. In addition, the sorption density of borate by D-LDH calcined at 700 degrees C decreased with increasing initial pH. The solid residues after the sorption of borate were characterized by FTIR, B-11 NMR ((11)Boron nuclear magnetic resonance), and XRD to explore the sorption mechanism of the calcined product at 700 degrees C.
