Cellulose based macromolecular chelator having pyrocatechol as an anchored ligand: synthesis and applications as metal extractant prior to their determination by flame atomic absorption spectrometry
Pyrocatechol is immobilized on cellulose via ---NH---CH2---CH2---NH---SO2---C6H4---N=N--- linker and the resulting macromolecular chelator characterized by IR, TGA, CPMAS 13C NMR and elemental analyses. It has been used ...
8-Hydroxyquinoline anchored to silica gel via new moderate size linker: synthesis and applications as a metal ion collector for their flame atomic absorption spectrometric determination
The silica gel modified with (3-aminopropyl-triethoxysilane) was reacted with 5-formyl-8-hydroxyquinoline (FHOQx) to anchor 8-quinolinol ligand on the silica gel. It was characterised with cross polarisation magic angle ...
