Rice husk ash produced by burning raw rice husk at 500 °C was used at volume of 100, 150, 300 and 450 cm3 and treated with saline water with electrical conductivity 23 dS m-1 with two volumes 200 and 300 cm3 .

Saline water was passed through rice husk ash for 30 minutes.

After that some of chemical properties of saline water were determined such as electrical conductivity (EC) , sodium adsorption ratio (SAR) and soluble ions concentration ( Ca+2 , Mg+2 , Na+ , K+ , Cl- , SO4 -2 and HCO3 - ).

Rice husk ash was showing high ability in reducing all of studying properties with percentage 90.04 % , 82.90% , 83.00% 98.99% , 96.94 % , 86.11% , 96.94% , 91.30% and 88.61 % respectively.

The volumes of rice husk ash 300 and 450 cm3 were showed high significant effect compared with other treatments in reducing all values of studied properties.
