摘要
Abstract
The main mineral phase in the raw bentonite sample sourced from Ningguo, Anhui Province is Ca-montmoriilonite. The impurities in the Ningguo bentonite, including zeolite, feldspar, and quartz, etc., have been proved to be removable by using the finely controlled sedimentation method. And the purified Ningguo bentonite can be converted into Na-activation process by using Na2CO3.The high quality Na-bentenite is obtained based on a combined study by the powder X-ray diffraction, the fourier transform infrared spectroscopy, the scanning electron microscope, the thermogravimetric (TG) analysis etc. The obtained fundamental information would be of both theoretical and experimental meaning for the potential industrial applications of Ningguo bentonite.关键词
