The use of the palygorskite of Iraq as an adsorbent for the removal of Pb from aqueous solution was investigated by the mean of batch technique. Iraqi palygorskite was collected from Digma and Akashat Formations (Masstrachtian and Danianage) from the western Iraqi Desert. Palygorskite exists within the clay-rich sediments; therefore it was concentrated by separation from clay fraction. A series of adsorption tests were conducted to analyze the sorption mechanism and capacity of palygorskite. Standard solutions of Pb were prepared with known concentrations (10, 25, 50, 75, 100, 125, 150, 175, 200, 225, and 250 ppm). Each solution was mixed with 1gm of palygorskite, and treated with total volume up to100 ml for 1hr with stirring at temperature of 25°C. The treated palygorskite was then separated by filter paper. Each filtrate solution was subjected to physical and chemical measureme.. View More»
