Abstract:
The X-ray fluorescence technique is used to determine different types of materials in its different states solid, liquid, powder, gas and other form.
It was used to determine most kinds of material in the method it is fast, accurate and nondestructive and usually requires only a minimum of sample preparation.
The precision and reproducibility of XRF analysis is very high, very accurate, results are possible when good standard specimens are available.
In this thesis one of most important application of X-ray Fluorescence techniques (XRF) with the helium system for liquid analysis was used to determine traces elements which exist as composition of any samples of water.
Due to importance of water for life two different sources of water were presented to determine the trace elements which dissolved on each sample with varying the temperature (80C , 320C and 900C) the river water and purified water. The applied procedure allows determination of various elements in broad concentration range of analyzed elements as function of temperature variation.
The techniques reveals accurate results as a function of temperature it was found that some elements disappear under certain temperature while some element appear.
