Processes occurring in ultrasonic treatment of aqueous suspensions of gibbsite and zinc oxide of basic zinc carbonate were studied. It was found that, in treatment of suspensions of gibbsite and zinc oxide, ZnO particles become coarser, whereas in mixtures of gibbsite and Zn4CO3(OH)6·H2O, articles of basic zinc carbonate are dispersed. The size of gibbsite particles in both formulations remains nearly unchanged. It was shown that a preliminary ultrasonic treatment of sorbent components make it possible to raise the static capacity for HCl vapor. It was found that Zn5(OH)8Cl2·H2O (mixture with zinc oxide) or Zn2OCl2·2H2O (mixture with basic zinc carbonate) is formed in this case, which leads to a higher sorption capacity of the latter.
