Preparation of sinapinaldehyde modified mesoporous silica materials and their application in selective extraction of trace Pb(II)
A new solid phase extractant, sinapinaldehyde (SA) modified SBA-15 mesoporous silica, was developed for selective extraction and preconcentration of trace Pb(II) from aqueous solutions. The successful immobilization of SA on SBA-15 and the strong interaction between SA-SBA-15 and Pb(II) were charact...
