Immobilization of tetrabutyl thiuram disulfide in chitosan thin film for sensing zinc ion using surface plasmon resonance spectroscopy
Tetrabutyl thiuram disulfide (TBTDS) immobilized in chitosan thin film has been studied as a sensor element for zinc ion, Zn2+, using surface plasmon resonance (SPR). The TBTDS-immobilized chitosan thin film, which acts as an active layer, was coated on a gold film by spin coating. Zn2+ can be detec...

| description | Tetrabutyl thiuram disulfide (TBTDS) immobilized in chitosan thin film has been studied as a sensor element for zinc ion, Zn2+, using surface plasmon resonance (SPR). The TBTDS-immobilized chitosan thin film, which acts as an active layer, was coated on a gold film by spin coating. Zn2+ can be detected by measuring the SPR signal when TBTDS-immobilized chitosan thin film contacts with Zn2+ in solution. The sensor produced a linear response for Zn2+ ranging from 0.1 to 1 ppm with a sensitivity of 0.0317 degrees ppm(-1). Using immobilized TBTDS as an active layer, the Zn2+ can also be selectively detected when present in mixtures of heavy metal ions. |
