The security of heavy metals in the mudfult soil Wang Li Environmental Science
Content Materials Method Anticipated result
Materials: 1 Mudflat soil from Rudong 2 Sludge from Tangwang sewage treatment plant 3 Sorghum sudanense
What is sorghum sudanense It is an annual herb belongs to Gramineae sorghum A species of grass raised for forage and grain Native to tropical and subtropical regions of Eastern Africa.
Why is sorghum sudanense Salt- resistant plants Drought-enduring plants The vegetative cycle of sorghum sudanense is very short
Method: 1 Mixed mudflat soil with sludge in different proportion: 0% 5% 10% 15% 20% 2 Plant sorghum sudanense in the mixture 3 When the sorghum sudanense ripe ,we will test heavy metal(Cd Cr Cu Ni Pb Zn)in its body.
