| Abstract: | The components and characters of humus in irrigation farmed gray brown desert soil were studied and gel filtration method is used at indoor experiment to study them bond properties of the foreign source 137Cs and soil humus’ components. Results show that the bonding rate of 137Cs was the highest in clay mineral, 78.37% of total. 21.63% of 137Cs was accumulated in the humus, the bonding rate of 137Cs with humic acid, fulvic acid, and humin were 5.78%, 6.60% and 9.25%, respectively. The humic acid and 137Cs formed four low weight complex moleculars, their average molecular weights are > 700,392,168 and <100 But humic acid and 137Cs can not only be bonded into the stable organic inorganic composite, but also into humus-metal ion complex with very high stability. |
| Keywords: | 137Cs irrigated farmed gray brown desert soil humus component mass average molecular weight |
