Abstract :
Ion sensors particularly organic fluorescent
chemo sensors are very much researched in recent times
for detection of metal ions in food and especially water
more so in the third world countries. Their significance
lies in the ease of use, solubility in aqueous medium, and
comparatively cheaper alternative to sophisticated
techniques such as AAS, ICP-AES or ICP-MS. Cu (II)
ions play a vital role in the physiological system of living
organisms and is required to be present within a
specified range so as to avoid complications by either
being deficient or abundant than the specified limit by
WHO. This paper reports thesynthesis of a novel watersoluble fluorescent Schiff baseas a chemoselective metal
ion detector for Cu (II) ions. It displays favorable
quenching of fluorescence for Cu (II) ionsfrom amongst
a wide range of other metal ionswhich are commonly
present in food and drinking water. The sensor has a
detection limit of 1.44μM which is much less than the
permissible limit of 31.4μM for Cu (II) ions as specified
by WHO. The novel chemo sensor thus synthesized
provides rapid, selective and a highly sensitiveresponse
to Cu (II) ions which provides the scope of this chemo
sensor in being developed further into becoming the
sensor of choice for the determination of Cu (II) ions in
water samples.
