This study describes a super paramagnetic magnetite Fe3O4 nanowafers adsorbent, using for the completely removal of some heavy metals (Fe+2, Mn+2, Cu+2, Zn+2, Ni+2, Pb+2, and Cd+2) from three discharge industrial wastewater samples which consider some pollution sources that submerging in the River Nile. For adsorbent the effect of various parameters such as the initial concentration (100 – 300 ppm), the mass of adsorbent (0.5 – 3 gm), the contact time (1-3 ml/min) and the solution pH (2-10) were determined of Cd metal ions by breakthrough determination. The maximum removal efficiency was found to be 100% in 1gm of SPMMFe3O4 NWNPs per 4572 ml at 25 mg/l (10 mg/l Fe+2, 4 mg/l Mn+2, 3 mg/l Ni+2, 2 mg/l Cu+2, 2 mg/l Zn+2, 2 mg/l Pb+2, and 2 mg/l Cd+2 ) of industrial discharge wastewaters were collected from the El-Nasr Company for Coks, Chemicals, Egyptian Iron and Steel factory and Egyptian Sugar & Integrated Industries Company at pH= 7.However, the AMBERLITE IR 120 H resin obtains result 2914.65 ml at the same conditions, this means that the efficiency of super paramagnetic magnetite Fe3O4 nanoparticles on a resin (AMBERLITE IR 120 H) supportis greater with 36.25 %. The next step in this work will consist of testing this non-conventional adsorbent on a pilot industrial scale. |
