A Study to the Factors Influencing the Plants Absorption of Heavy Metals
In order to master the rule of heavy metals migration on the interface of tailings-plants and how matrix physicochemical characteristics change,pot experiment was conducted with/without soil,choosing PAM and EDTA as tailings modifiers,with/ without organic matter.The results showed that: the existence of soil inhibited the absorption of heavy metals,especially for Cu,to which significant inhibition effect has been achieved,join of EDTA and PAM could further restrained the leafy plants to absorb heavy metals.The experimental results also indicated that PAM had a significantly adhesive effect on soil particles than EDTA,improved the soil structure to a certain role,each matrix pH value varies between 7-8,and there are no significant difference between PAM and EDTA processing matrix.
