Hydatidosis, a zoonitic parasitic disease, is one of the most important economic and health problem in Iraq and many other countries in the Middle East. It is caused by Echinococcus Multilocularis and Echinococcus granulosus, the larval stage of which is localized in the liver, lungs and other visceral organs of intermediate hosts such as sheep, goats and cattle.Human are considered to be an accidental intermediate host, either by eating improperly disinfected vegetables or by close contact with dogs.

 The subject of this thesis involves studying the possibility removed of four organic compound by TiO . These organic compounds (considered as pollutants) which are; Birlliant blue (dye), polyvinyl alcohol (PVA), Linear alkyl benzene sulfonate (LAS) and Lambdacy holothrin as (pesticides). The thermal and photo-stability were studied and the results showed that all pollutants are stable in temperature range about (288-318) K, and stable against UV-linght in the wave length range (290-320) nm.

Amiloride hydrochloride ion-selective electrodes were constructed in polymeric membrane by using PVC and based on the use of active ion-pair (Amiloride - phosphotungstate) and the other ion pair (Amiloride-tetraphenylborate) with the following plasticizers: Di-butyl phthalate (DBPH), Di-octylphthalate (DOP) and Tri-butyl phosphate (TBP). The properties of these electrodes were studied, including: slope, correlation coefficient, concentration range, detection limit and life time.
