Description

Extraction of iron and manganese from sediments using 0.5 N HCl with hydroxylamine hydrochloride in anaerobic conditions, followed by ICP-AES analysis. This method targets metals associated with reducible phases in sediments.

Typical Equipment

  • HDPE bottles
  • 0.5 N HCl
  • 0.25 N hydroxylamine hydrochloride
  • 0.45 μm filters
  • ICP-AES

Output Measurements

  • extractable iron concentration
  • extractable manganese concentration
