Lanthanide-based chemosensors for the detection of environmentally and biologically relevant ions

posted on 2021-03-22, 21:57 authored by PARVATHY MINI RADHAKRISHNAN NAIR
Hydrogen sulfide is a chemical species known for its characteristic smell of rotten egg, and it is extremely dangerous to humans as well as to the environment due to its high lipid solubility, even in trace amounts. So it is highly necessary to track its presence and accumulation over time in the environment. This thesis is mainly focused on the development of lanthanide-based chemosensors for the detection of hydrogen sulfide in both aqueous and gaseous state. The chemosensors were successfully developed and they exhibited a fast, sensitive and selective detection of hydrogen sulfide even in trace amounts.They were later utilised to detect hydrogen sulfide in biological (rat plasma) samples. Lastly, the thesis discusses the development of a colorimetric sensor for the detection of ammonia in water samples utilizing a microfluidic device
