Titanosilicates of enhanced ion exchange capacity and their preparation
Patent
·
OSTI ID:5869481
A method is described for increasing the ion exchange capacity of a titanosilicate without increasing acid activity of the titanosilicate which comprises contacting the titanosilicate with an aqueous alkaline solution having reactant anions selected from the group consisting of SO/sub 3//sup -2//OH/sup -/ and OH/sup -//NH/sub 4/NO/sub 3/ and having a pH ranging from about 7 to about 10 ''under conditions effective to increase the ion exchange capacity without increasing acid activity''.
