Description

Nanoscale magnetite bearing magnetic carrier with an adsorbed layer of dibenzo-18-crown-6 was evaluated for removing radionuclides from nuclear waste solutions using magnetically assisted separation method. TEM results indicate that the average size of the base magnetite particles is ∼19 nm. The results of Moessbauer spectroscopy and field cooled (FC) and zero field cooled (ZFC) magnetization confirm the superparamagnetic behaviour of the magnetite particles in the polymer beads at room temperature and hence meet the requirement of magnetic filter regeneration capability
