ACID MODIFICATION OF BENTONITES OF VARIOUS CHEMICAL COMPOSITION
Modification of bentonites mainly from deposits of the Chechen republic of the various chemical composition activated and organomodification in water solutions of some acids depending on their concentration and duration of process is investigated. It is found that of all the samples of bentonite, irrespective of concentration and acid phylum, with varying speed intensively extracted the same chemical elements (calcium, iron, magnesium, sodium, aluminum), pulling together chemical composition of the modified samples. It has been shown that the rate of this process is considerably higher the initial period modification of bentonite. Depending on chemical composition of bentonite in the course of modification it is possible to extract cations also weak organic acids.
