Preparation and structure research on one kind of second-insert organic bentonite

摘要

The Na-bentonite prepared with the bentonite from Pingliang, Gansu Province were second-inserted in the reagent of transition metal salt and cetyl trimethyl ammonium bromide(CTAB). The burning rate of the second-inserted organic bentonite can reach 22%. Researching with the method of FT IR and XRD, the results of X-ray diffraction show that the spacing of this second-inserted organic bentonite layers increases from 1.415nm to values 3.002nm.
