SORPTION PROPERTIES OF POTASSIUM POLYTITANATE NANOPARTICLES DOPED WITH NICKEL IONS

Using the method of coprecipitation followed by hydrothermal treatment, nanoparticles of potassium polytitanates with titanium atoms shielded with nickel in amounts from 2,5 % to 10% were obtained. According to scanning electron microscopy, quasi-one-dimensional nanoparticles are formed during synthesis. The paper presents the results of a study of the sorption properties of potassium polytitanate nanoparticles doped with nickel, using the example of a reaction with the model dye methylene blue.
