Scientific interests: - Natural adsorbents (zeolites, kaolinite, saponite, talc, diatomaceous earth, humic acids, and brown coals); -Studies of the physicochemical properties of natural adsorbents (porous structure, morphology, crystalline structure, thermostability, photoluminescence, and surface chemistry); - Studies of adsorption processes (kinetics, isotherms, thermodynamics, and diffusion); - Modification of natural adsorbents; - Adsorption of xenobiotics (heavy metals, organic compounds) from aqueous solutions, sewage and sewage sludge; - Studies of adsorption under static and dynamic conditions; - Cultivation of unicellular algae diatoms under laboratory conditions; - Production of diatom biomass and diatomaceous biosilica; - Metabolic doping of 3D structured diatomaceous biosilica; - Chemical modification of diatomaceous biosilica; - Synthesis of hybrid composites of diatomaceous biosilica doped with metal nanoparticles (Ag, Pd, Ti, Ge, V, Nd, Ce, and Tb); - Production of diatom biomass for the extraction of bioactive compounds with potential benefits for human health (biosilica, many unsaturated fatty acids, and carotenoids).
