Water contaminated by heavy metals remains a serious environmental and public healthproblem. The toxic effects of heavy metals on the biosphere have been demonstrated by a number ofstudies. Since the main sources of heavy metals for humans are water and food, the monitoring of theheavy metals content in natural water is of paramount importance. Diverse technologies have beenused to reduce the contents of heavy metals in water. Recently, adsorption methods have been widelyused because of their low cost. The novel nano-water-purifying material used in our work iscomposed of AlO(OH) nanoparticles loaded onto glass fibre and supported by active carbon felt. TheAl nano-powder starting material, was prepared using an electric explosive technique. The productswere characterized by X-ray diffraction, scanning electron microscope, transmission electronmicroscope, and BET techniques. It was found that the particles consisted of AlO(OH) nanofibres ofpure boehmite structure. They exhibited a surface area of 431.7 m2 / g. The composite material wasfound to be effective in removing cadmium from dilute aqueous solutions and could find broadapplication in heavy metal removal
