Can we apply the estimation of cu2+ ions using calorimetric method for the analysis for other metal ion?
Answers
The Cu2+ ion plays an important role in a number of biological processes, including iron absorption, haemopoiesis, various enzyme-catalyzed and redox reactions. Abnormal levels of copper ions can lead to vomiting, lethargy, increased blood pressure and respiratory rates, acute haemolytic anaemia, liver damage, neurotoxicity and neurodegenerative disease. Furthermore, copper ions can disrupt natural ecosystems due to their adverse effects on microorganisms4. Therefore, the development of selective and reliable detection methods for Cu2+ ions is of significant interest to the scientific and environmental communities.
A number of analytical methods have been developed for the accurate determination of Cu2+ ions, including atomic absorption/emission spectroscopy (AAS/AES), inductively-coupled plasma mass spectrometry (ICP-MS), electrochemical methods and X-ray fluorescence spectroscopy (XRF). However, these techniques involve time-consuming sample pre-treatment methods and/or the use of sophisticated instrumentation, thus precluded their application for in-field detection of Cu2+ ions. This has stimulated the development of a variety of small molecule probes for the rapid and sensitive detection of Cu2+ ions
