The Introduction Bismuth one of the most important

The aim of the experiment is determination of a mount of bismuth in Pepto-Bismol antacid tablets using Atomic Absorption Spectrometer instrument (AAS) and inductively coupled plasma-optical emission spectroscopy (ICP-OES) instrument. As well as to see the interpretation of the resultant data from the instruments programs using curves and correct calculations.

Bismuth one of the most important components to treat gastro-intestinal illness, for example, diarrhoea, heartburn. Bismuth is found in sea water. However, increase of bismuth in the body could be effect on the liver and kidney ()

There are some techniques used to determine amount of bismuth, First,

atomic absorption spectroscopy(AAS), this a technique for quantitative fixing of minerals by transference of a sample to atomic steam and gauge of absorption at a wavelength specified to the trace of benefit. Atomic absorption spectroscopy is one of the most considerable equipment in analytical chemistry, the(AAS) is use the absorption of light to gauge the concentration of gas -phase atoms.

The analyte concentration is measured from the value of absorption. The determination of known concentration with standard by using calibration curves after calibrating the instrument. (AAS) has a lot of uses in chemistry, for example, water analysis, clinical analysis pharmaceuticals.

Second, inductively coupled plasma optical emission spectroscopy ICP-OES is an analytical technique used to metals and it is a type of Spectroscopy that uses the inductively coupled plasma to produce atoms and ions. ICP-OES is a trace-level, racial analysis technique that uses emission spectrum a sample to determine. can determine the samples through inserted into the plasma in a method that desolates, ionizes by their characteristic emission lines. The uses of inductively coupled plasma optical emission spectroscopy ICP-OES is trace analysis of water samples, environmental soil, Minerals and Healthcare. There are some problems such as the much high temperature ensures that the sample matrix does not produce any interfering components that vigoro hinder the analysis.

In addition, it is difficult to get accurate result without using the original standard, as well as there is no information on chemical form of sample.
