| Abstract: | This environmentally benign work describes a simple electrochemical sensor constructed with a chemically modified carbon paste electrode (CMCPE) using aloe vera xanthate nanoparticles to detect mercury ions. The characterization and morphology of nanoparticles were thoroughly investigated using modern techniques. The CMCPE efficiently senses the mercury ions. The limit of detection of mercury ions wasexcellent to the order of 0.231 μg mL−1. Real-time sample analysis showed promising results. The recovery range was between 99.4 % and 101.7 %. The activity of CMCPE was commendable even after fifty days. |
