|a Cement kiln dust is a major by product in cement manufacture. Methods of disposal, handling, treatment and reuses are a major factors in optimization of a certain cement plant. This thesis concentrates on the uses of cement kiln dust of souk Al Kamees cement plant as Soil amendment and as an adsorpent of Fe, Zn and lead results from sand. The major objectives of these treatments are environmental rather than economical to reduce the landfill disposal of CKD which is major problem in cement industry. CKD is used in agricultural soil amendment. CKD in Souk Alkamees consists primarily of calcium carbonate and silence dioxide, the alkaline by pass process contains highest amount of calcium oxide and lowest loss on ignation [LOI] which become a beneficial for CKD use as a soil amendment to the sand for many especial agricultural products such as potatoes, …etc. This thesis concentrates on the uses of CKD as an adsorbent to remove heavy metals such as Fe, Zn, and Pb from soil. Adsorption column is used to perform the work. Experimental setup discussed in the thesis is used using cement kiln dust as an adsorbent for removal of heavy metals from soil. The major result is to simulate the physical behavior of the process using conventional isotherms available in literature, Langmuir, Freandlish and Drachsal isotherm models have been found to simulate the data with good agreement with experimental work. Characterization of the CKD is made after dehydration process at 150C for 24 hrs. X ray fluorescent equipment is used and the results are reported in the thesis.
