合成丝光沸石（1.0g）的Cs溶液的ppm为约1.0ppm。100%和CA。在100mL水和海水中，分别为83%。以丝光沸石和纳米磁铁矿的混合料浆为原料，合成了丝光沸石和纳米磁铁矿的复合粉体材料。对于含20和30wt%磁铁矿的复合材料，使用钕磁体的复合材料的磁收集率大于90%。含20wt%和30wt%磁铁矿的复合材料在吸附水中Cs +后使用磁收集的总Cs净化率分别为92.7%和97.2%。
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.
