• Removal of Lead from Water by Sorption on Kaolinite Clay
    Vol. 2 No. 2 (2019)

    This work demonstrates a description, experimental results and a design of a water treatment apparatus. The apparatus was manufactured to remove the lead metal from contaminated water by continuous pumping principle. This method depends on adsorption of lead ions by Iraqi clay metals surface as kaolinite. In this work counted amounts of clay metal were saved in several cloth bags to guarantee a wide use of clay and consequently a larger surface area. The bags were put inside a vertical container with quantities of glass small pipe pieces to increase the volume and the surface area. This container was placed completely inside another container. The contaminated water passed throw a pipe to the internal container which contains the clay metal from down direction to upper direction of the container, to fill it and flood to the outer container which has an exit pass of the pure water. The lead contaminated water was taken (10 ppm) from a storage tank through a pump with flow meter to inter the purifying container . For testing purposes the outlet purified water was analyzed by atomic absorption device. The experiments indicated that 5 grams of the clay can remove 100 mg of lead from 10 liter of water by a flow rate of 0.05 liter/min.
