Preparation and Adsorption of [Bis(1,10-phenanthroline) nitratolead(II)]nitrate Complex on Activated Carbon and Zeolite Surfaces

Abstract

In this research the complex [Bis(1,10)-phenanthroline) nitratolead (II)] nitrate was prepared and the adsorption of the complex on (activated carbon, zeolite and mixture of them) was studied in equal weights under various conditions such as: temperature, contact time, pH and the change in the weights of adsorbents. With respect to activated carbon, the adsorption quantity was increased at: (30-50)C0 and (60-90) min, the suitable weight of activated carbon for adsorption was (0.15)g at pH (9). Zeolite, the adsorption quantity was increased at the temp. reached (50)C0 in a contact time lower than (90) min at a critical weight (0.3)g and pH(9). Finally when both adsorbents were mixed, the adsorption quantity was increased at temp. reached (50)C0 with the range of time (60-90) min in a weight (0.25)g at the range of pH(5-11).
