Research on Eliminating Hardness in Water by Mesoporous Material

摘要

Hardness in water, which judges the water quality, impacts greatly on the human health according to the relevant researches appropriate treatment of corresponding high hardness water is urgently necessary. This paper reports the preparation of mesoporous silicon material by the application of sol-gel method, where the template was cetyltrimethyl ammonium bromide and the silicon source was tetraethoxysilane Using X-ray diffraction, Fourier transform infrared spectroscopy and polarizing microscope, a series of corresponding researches on phase composition, chemical composition and microscopic crystal morphology of the synthetic mesoporous material were carried out Its property of removing hardness in water was also tested by static adsorption experiments. The results show that the synthetic mesoporous material has certain absorption efficiency as to cope with the total hardness eliminating problem in water and which is advanced by high purity and low crystallinity.
