Zeolite-SPION Nanocomposite for Ammonium and Heavy Metals Removal from Wastewater

SPION-decorated organofunctionalized MCM48 silica-based nanocomposites for magnetic solid-phase extraction

“…The correlation between SPION content and Magnetic Saturation was previously described in our work about magnetic zeolite for wastewater treatment. 35 The comparative FTIR spectra of commercial SiO2 and synthesized MCM48 depict similar peaks (see Fig. 2).…”

Nanocomposite substrate-supported nanofiltration membrane for efficient treatment of rare earth wastewater

“…In the rare earth smelting and separation process, due to processes such as saponification of the extractant, a large amount of ammonia nitrogen wastewater would be produced, which contains high concentrations of calcium and sodium ions, accompanied by a small amount of radioactive elements and heavy metals. The composition of rare earth sewage is complicated and difficult to treat [4,5]. If discharged directly without treatment, it would cause great harm to the environment.…”
