Title: Study on the Surface Acidity of Hydroxyl-Aluminum Montmorillonite
Abstract:The total acidic amount and its strength distribution of various hydroxyl-alum-inum cross linked montmorillonites (Al-Mt) with different concentrations of Al3+ ion and OH/Al molar ratios have been stu...The total acidic amount and its strength distribution of various hydroxyl-alum-inum cross linked montmorillonites (Al-Mt) with different concentrations of Al3+ ion and OH/Al molar ratios have been studied by absorbed indicators and n-butylamine titration methods. The results show that surface acidities of Al-Mt are stronger than Na-Mt. There are essentially no influence on the surface acid for the concentrations of Al3+ ion and OH-Al ratios of the cross linking agent, but the surface acid decrease with increasing of calcination temperatures are significant.Read More
