dc.description.abstract The effects of excess Sodium (Na) on Cobalt (Co), Cadmium (Cd) and Barium (Ba) were studied using the inductively coupled plasma-optical emission spectrometry (ICP-OES). The emission signals of the analytes with the inteferent were evaluated as E’/E and plotted against the concentration. Readings were taken between 0-10mg/l for Cobalt and Cadmium whilst for Barium; readings were taken from 0-30mg/l. The experimental graphs revealed that there is an effect of the intereferent on the signal emission. Comparisons were made using the theoretically calculated graphs from which a derivative and applicable theory to explain the experimental graphs was simulated. The theories explained variables in which ΔE = 0, ΔE = IP (int) - IP (anal) and ΔE = kt -IP (anal) in which ΔE is the change in energy. These were used to simulate the relationship between the experimental and the theoretical graphs. However a close relationship was realised between the graphs. en_US
