Research of the sorption properties of a sorbent based on nano-sized carbon in relation to La(III) ions and optimization of the conditions for its sorption using mathematical modeling
Abstract
This research describes the sorption of lanthanum(III) ions by nanosized carbon particles with a particle size of 10 - 100 nm with a maximum of 30 nm. The sorption properties of nano-sized carbon in relation to lanthanum (III) ions were researched. It has been established that the sorption of lanthanum(III) ions by nanosized carbon particles is described by the Langmuir model. Optimization of sorption conditions made it possible to achieve a high sorption activity of nanocarbon towards lanthanum(III) ions of 87 %. A high sorption efficiency of nano-sized carbon was revealed in comparison with literature data. A mathematical model of the sorption process, calculated using OpenFOAM software, is presented, with the maximum concentration of lanthanum(III) ions observed on the surface of the sorbent.
