Paper Abstract

Solid phase luminescence determination of aluminum using UV laser and optical multichannel spectra analyser (OMA) was descnbed Silica (SG) modified sith ion associate high molecular eiglu quatemar ammornurn salt (QAS) lumogallion (LG) was used as active sensor element Photoluimnescence (PL) of the modified sorbent as excited b) pulse N2 laser and then studied by OMA using CCD camera for detection of the pulse PL spectra and IBM PC for analyses It was shown that the intensity of PL pulse peaks of the modified SG noticeabl increased ith the nsing of Al (III) concentration in the range of 1 10-6 ÷ 1 10-4M. The detection limit of Al as 1 10-7 mole/1 at sample volume 50 ml and mass of the sorbent 0.05 g. PL spectra of Al-LG complex formed on the surface is consisted of two bonds Their possible reasons are discussed The developed method can be successfully used for working out optical sensor for aluminum determination in the environment.
