Preparation of 5-Sulfosalicylic Acid Modified Silica Gel and its Adsorption Performances for Lead

Abstract:

A new sorbent (SSA-SG) with 5-sulfosalicylic acid as functional group has been prepared and characterized with FTIR and then used as micro-column packing for enrichment of Pb (II). Enrichment conditions of lead were optimized. The enrichment factor reaches 200 and the dynamic sorption capacity was 15.46 mgg^-1for Pb (II). The proposed column enrichment procedure was applied for the preconcentration/separation and atomic absorption spectrometry (AAS) determination of Pb (II) in water samples successfully.
