The identification and quantification of the mineral elements play a significant role in environmental and biological sciences. According to the reports, barium (Ba2+) is considered to be an accompanying element to calcium, which is essential at tracelevels.However, at higher concentrations, barium compounds exhibit serious taxological effects on various living systems, and is considered as a physiological antagonist of K+ ion. According to the recent opinion, Ba2+ ion can block K+ ionchannels of the Na K pump in the membranes of cells, increasing active influx and inhibiting passive efflux of K+ ions. It acts as a muscle poison that causes cardiac and gastrointestinal irregularities, and paralysis. In view of this, several research groups have been explored analytical protocols for the detection of Ba2+ ion in environmental samples using various analytical techniques such as graphite furnace atomic absorption spectrometry, UV-visible spectrometry, ion-chromatography, inductively coupled plasma-mass spectrometric, inductively coupled plasma atomic emission spectrometry
