This paper reports a simple and highly selective method for the preconcentration and separation of trace Hg(II) with aminopropylbenzoylazo-2-mercaptobenzothiazole bonded to silica gel (ABMBT.SG). ABMBT.SG was tested for the selective extraction of Hg(II) and it showed an exchange capacity of 41.4μmolg -1 . After preconcentration and separation using an ABMBT.SG column, trace Hg(II) in...
Hg(II) imprinted and non-imprinted copolymers were prepared by metal ion imprinted polymer (MIIP) technique. The copolymers were obtained by copolymerizing mercury chloride (or without it), diazoaminobenzene (DAAB) and vinylpyridine (VP) using ethyleneglycoldimethacrylate (EGDMA) as cross-linker in the presence of 2,2′-azobisisobutryonitrile as initiator. The separation and preconcentration characteristics...
