Chemistry, Physics and Technology of Surface| Резюме: | Phase composition of samples of both natural basalt tuff from two Ukrainian deposits and its chemically modified forms have been studied. It has been found that the ratio of main phases of clinoptilolite, mordenite, and montmorillonite depends on the mineral origin and its chemical modification method. Some structural changes take place only in montmorillonite phase after both treatment of natural basalt samples in boiling 3M HNO3 for 9 and 12 h and fixing Pd(II) and Cu(II) on it. The activity of Pd(II)-Cu(II)/H-BT catalyst in the reaction of carbon monoxide oxidation decreases when the content of montmorillonite phase in natural basalt tuffs diminishes. |
