【摘要】 为了寻找能阻滞锝、碘迂移的地质材料。本工作研究了黄铜矿,方铅矿、稀土赤铁矿,辉锑矿,辉钼矿,黄铁矿等六种矿物对碘和锝的吸附和解吸。结果表明黄铜矿,方铅矿对碘的吸附较好(R_d≈100mL·g^-1),辉锑矿对锝的吸附能力相当强(R_d≈2×10³mL·g^-1)。吸附是不可逆的,被吸附后的核素牢固地留在矿物上。更多还原

【Abstract】 In order to look for some geologic materials that can retard technetium and iodine on them. The work has researched in adsorption and desorption of iodine and technetium on brass ore, lead glance, rare-earth hematite, antimony glance, molybdenite and iron pyrites and so on. The results indicate that brass ore and lead glance have rather good ability adsorbing iodine (Rd=100mL. g-1) and antimony glance for technetium(Rd=2 X 103mL . g-1). These kinds of adsorptions aren’t inverse. Adsorbed nuclides were hard kept by those ores.更多还原
