  1. 1. The security of heavy metals in the mudfult soil Wang Li Environmental Science
  2. 2. Content Materials Method Anticipated result
  3. 3. Materials: 1 Mudflat soil from Rudong 2 Sludge from Tangwang sewage treatment plant 3 Sorghum sudanense
  4. 4. 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.
  5. 5. Why is sorghum sudanense Salt- resistant plants Drought-enduring plants The vegetative cycle of sorghum sudanense is very short
  6. 6. 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.
  7. 7. Laboratory instrument Atomic Absorption Spectroscopy(AAS)
  8. 8. Data processing Absorbance concentration Standard curve A ? Content(metal)=C*V/m Illustration: C:concentration V:the volume of the leaching liquor m:mass of the soil or plants
  9. 9. Anticipated result The heavy metals in sorghum sudanense plant in the mudflat soil which mixed with sludge can meet the plant in vivo heavy metal content requirements
