| Summary: | Sol-gel technique was used in this study for sensing material preparation which
could be used for aluminium detection in aqueous environment. Two organic
reagents i.e. eriochrome cyanine R (ECR) and chrome azurol S (CAS), which
are sensitive to aluminium were used in this study. The precursors used for the
sol-gel solution preparation were tetraethyl orthosilicate (TEOS), water and
ethanol in the volume ratio of 30:31:30. Dip-coating method was used to
deposit the sol-gel solution onto microscope slide glass support to produce a
thin sol-gel film. The study shows that the immobilised reagents have a good
photo-stability, still maintaining their chemical properties as in free solution
and regenerable by using NaF solution. The study also indicates that the reagen
doped in sol-gel film still react with the analyze and could be potentially used
as sensing material for aluminium detection. |
