Abstract: With modified sequential extraction and separation analysis method, lead in tea garden was divided into six fractions: water soluble, exchangeable, bound to carbonates, bound to Fe-Mn oxides, bound to organic matter, and residual. All the six forms of lead and total lead were determined with ICP-OES, showing that this method has good precision ,accurate, reliable and easy to operate.
