A simple flow injection with flame photometric detection has been developed for determination of sodium, potassium, and total alkalies in portland cement, fly ash, admixtures, and water of concrete. A liquid sample or a digest of solid sample was injected into a water carrier stream which flowed to a flame photometer. A change in emission intensity at a selected wavelength was recorded as a peak.
In this paper, we have investigated 18 water samples collected from various sources, e. Along with it, water quality index WQI is calculated to evaluate whether the collected surface, ground and river water samples are fit for human consumption for the residents of those areas. WQI values of all the samples are found to be less than 50, which indicates they are safe to consume by the humans. The possibility of employment of characteristic emission from excited atoms in quantitative analysis of elements for analytical chemical science was first experimentally studied by Bunsen and Kirchhoff. For the detection of trace metals all across the world, atomic emission is considered as an effective tool.

Hydroelectrolytic disorders are common in clinical situations and may be harmful to the patient, especially those involving plasma sodium and potassium dosages. We analyzed samples in the three different methods cited from patients attending the laboratory of the University Hospital of the Federal University of Juiz de Fora. The values obtained were statistically treated using SPSS The present study aims to evaluate the impact of the use of these different methods in the determination of plasma sodium and potassium. The averages obtained by the colorimetric enzymatic method presented statistical difference in relation to ISE , both for sodium and potassium.
