Recovering of heavy metal ions Zn(II), Cu(II) and Mn(II) in aqueous solution has been investigated using a novel nano silica modified by hemtaprophyrin. Nano sorbent was prepared by sol gel method. Transmission electron microscope and EDAX analysis showed the nano scale with porosity of a new sorbent. The proposed structure of modified silica with HP was predicted according to FTIR and elemental analysis. The new sorbent have good thermal stability. The phenomena of the sorbent sorption included the static studies such as pH and the Langmuir and Freundlish models were applied at equilibrium state. The linear regression analysis was Langmuir isotherm according to the values of relation coefficient (R2). The limit of detection (LOD) for Zn, Cu and Mn were 0.01, 0.12 and 0.03 μg L-1 respectively, within the analytical range 0.1-10 μgL-1. This method achieved highly precision for the samples of environmental and pharmaceutical formulations of % RSD less than 10%.
