Description
Summary:Results obtained shows a linear relationship between the output light intensity and iron concentration, illustrating the functionality of this iron optical sensor. Traditionally, several methods have been introduced to detect iron concentration such as atomic absorption spectrometry (AAS) [3], [4] and inductively coupled plasma mass spectrometry (ICPMS) [5]. [...]these methods require expensive instruments that needs to be operated by specialists, meaning that they are not suitable to be used in-situ [10]. [...]they requires complicated procedure for chemical preparation and therefore becomes difficult for the routine implementation [11]. According to the literature, there are many developments that utilize the principle of EWA by employing different types of unclad fiber structure [26].
