研究了~(60)Co在土壤和矿物质中的吸附和解吸,在菜豆-土壤系统中的迁移、消长和分布。结果表明:(1)土壤、矿物质对~(60)Co吸附迅速,不易解吸。吸附率和分配系数大小排列顺序相同,为:硅藻土、青紫泥、黄红壤、高岭土、珍珠岩、粉泥土;解吸因数的大小
The adsorption and desorption of ~ (60) Co in soils and minerals and the migration, growth and distribution of ~ (60) Co in the kidney bean-soil system were studied. The results showed that: (1) Soils and minerals adsorbed ~ (60) Co rapidly and could not desorb easily. Adsorption rate and partition coefficient of the same order of magnitude, as follows: diatomite, brucite, yellow and red soil, kaolin, perlite, silt soil; desorption factor of the size
