English Abstract

The detection of water pollution using laser technique is considered as one of the latest methods for detecting tiny concentrations of pollutants, that are difficult to be measured by conventional methods.

A system for detection and measurement of water pollutants constructed.

It consists of a (5 mW He – Ne Laser) and its detection system, preparation unit and electronic detection system.

The detection mean by laser beam based on the principle of single beam laser light scattering technique.

A photomultiplier was used for detecting the transmitted laser light.

The effect of the pollutants concentration on the scattered light intensity was investigated using deferent samples to study; Turbidity, Hardness, Fungicide (Chlorothalonil), Drinking water, Heavy water and Khuryisan River.

A plot of the intensity of the scattered laser light and the scattering angle for the water samples can be estimated to have a Gaussian shape.

Its full width at half maximum (FWHM) is sensitive to the type and concentration of pollutants (C) in the water.

They obey relation of the form: FWHM = a exp(bC) where a , b are constants depend on the type of pollutants.

The effect of FWHM with pollutants concentration was investigate.

The pollutants concentration was decreased with increasing FWHM.
