Adsorption of heavy metals on natural zeolites: A review

Magnetically modified zeolite (MMZ) suitably combines the properties of zeolites and magnetic compounds (Maharana and Sen, 2021). The characterization of the magnetically modified zeolites shows that the presence of magnetic compound does not inhibit the natural zeolites frameworks and channels (Kragović et al., 2013b; Liang et al., 2011 ...
