Comparison with other sensors
Determination of iron species by optical sensor was compared
with other sensors used for the determination of iron species and
the outcome of which has been summarized in Table 4. Unfortunately,
to the best of knowledge, there are few reports on optical
sensors for the determination of Fe (II) and also a few articles have
been reported in the literature on optical sensors for determination
of Fe (III) and total iron. It was demonstrated that the suggested
optode is comparable to or even better than some sensors that
are available for iron monitoring. Moreover, the proposed sensor
offers low limit of detection in comparison to the sensors with
other supporting materials.
