treated form was investigated in acid (hydrochloric acid, lactic acid, acetic acid) and basic
(sodium hydroxide) solutions. Synthetic gastric juice (hydrochloric acid and 0.4% pepsin at
pH i= 2) was also prepared in order to examine the neutralizing capacity of zeolite for high
acid concentration of stomach. The change in proton and hydroxyl concentration with time
was studied by putting the different amount of zeolites into the various concentrations of acid …
