茶园土壤中铅形态的连续浸提测定方法研究

doi:10.13305/j.cnki.jts.2005.01.005

Abstract

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.

Key words: Sequential Extraction, Tea garden soil, Lead form, ICP-OES

CLC Number:

S153.6⁺1
