Popis:	ppm Cs solution for the synthesized mordenite (1.0g) was ca. 100% and ca. 83% in 100mL of water and seawater, respectively. The composite powder material consisting of mordenite and nano-sized magnetite was synthesized from a mixed slurry of the diatomite and nano-sized magnetite. Magnetic collection rate for the composite material using a neodymium magnet was larger than 90% for the 20 and 30wt% magnetite-containing composite materials. The total Cs decontamination rates using magnetic collection after the Cs + adsorption in water were 92.7% and 97.2% for the 20 and 30wt% magnetite-containing composite material, respectively.
