Adsorption of thiamine hydrochloride (vitamin B1) by synthetic layered silicates with a montmorillonite structure

The study of the sorption capacity of synthetic layered silicates with a montmorillonite structure towards thiamine hydrochloride was performed. The influence of the pH of the medium and the composition of montmorillonite on the thiamine adsorption degree was studied. The optimum chemical composition of montmorillonite was determined, which makes it possible to carry out an efficient intercalation of thiamine in a wide pH range.
