Abstract

Laboratory experiment was carried out in the laboratories of the college of Agriculture, University of Anbar to study the properties of sulfide water and processing methods for the disposal of hydrogen sulfide, which is toxic to humans, animals and plants alike. A treatments using were aeration, activated carbon, bentonite clay, nitric acid, hydrogen peroxide and manganese oxide, has been compared to the results of the processors in terms of rates of removal of hydrogen sulfide. The field experiment of the barley crop irrigated with water treated in various methods and untreated sulfide water compared with of the Euphrates River water and drainage water with electrical conductivity equal to the electrical conductivity of untreated sulfide water. The results showed that the best treatment for the removal of hydrogen sulfide are using nitric acid by removing 88%, followed by hydrogen peroxide treatment, removal by 77% and the least of which is the removal of treatment and ventilation by removing 40%. The results showed that more methods reduction of potential salinity was nitric acid is then followed by ventilation. All methods treatment led to an increase in dry weight and grain yield of barley crop compared with the weight of untreated sulfide water, but the increase was not significant for the treatment of bentonite and activated carbon while there is a significant increase for nitric acid, hydrogen peroxide and chlorine treatments
