Methods of the surface of seaweeds surface modifying, in order to obtain biosorbents for caesium with improved properties
The nuclear industry is one of the most developing in the energy sector. Nowadays the creation of a sorbent that effectively absorbs radioactive substances is very relevant. In this work, an iron ferrocyanide based biosorbent was created. High surface seaweed of Cystoseira barbata type were taken as carriers. Before the immobilization of the ferrocyanide phase by layer-by-layer assemble, the surface of the seaweed was modified with carboxylic acids. The structure of the produced sorbents was investigated by IR-spectroscopy method. It’s shown that sorbent samples obtained by layer-by-layer assembly have improved sorption properties. Equilibrium and kinetic characteristics of biosorbents in cesium sorption were studied.
