Why is it important?
Current analytical techniques such as atomic fluorescence spectrometry, atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectroscopy (ICP-OES), neutron activation analysis (NAA) and inductively coupled plasma mass spectrometry (ICP-MS) are highly sensitive but they are expensive to operate and maintain with limited life span. Moreover, these techniques require time-consuming manipulation steps, skilled technical persons and are unsuitable for in situ measurements. So, there is utmost need for alternate, cost- and time-efficient technologies for the real-time detection of metal ions.
Perspectives
The sensor was successfully used for the determination of metal ions content in lab samples. This sensor has a simple design, uses inexpensive materials and requires a short measurement time for analysis of metal ions in aqueous solutions. Contamination on the electrode surface can be removed by electrochemical cleaning.
