Abstract : The elimination of toxic heavy metals from aqueous environment has received considerable attention in recent years due to their toxicity and wide spread use. Adsorption by activated carbon has been widely used in water treatments because it has many advantages. Therefore in this study, New modified activated carbon were prepared (AC/TRIS – AC/DTZ – AC/DETADHBA) and the surface characterized by FT-IR before and after modification. Batch adsorption method was study to carry out the metal-binding ability of activated carbon that has been prepared. The effect of solution pH was studies for many metals ion to choose most favorable metal ion at optimum pH, Adsorption capacity of metal chosen was studied to determined maximum adsorption capacity and for representing the equilibrium states of an adsorption system. Effect of contact time was also investigated to understand the adsorption kinetics. Inductively coupled plasma optical emission spectroscopy was an appropriate instrument for determine ultra trace level of concentration of metal ions with high accuracy. Hexavalent chromium ion was selected to study with AC-TRIS at pH1, Auric ion was selected to study with AC-DTZ at pH1 and Lanthanum ion was selected to study with AC-DETADHBA at pH6. The efficiency of this methodology was confirmed by applying it to real environmental water samples with satisfactory results.
