Removal Of Toxic Cu++ In Presence Of Amino Acids

Howaida M.El-Kashlan

The rate of copper II/iron cementation reaction in presence of aminoacids as glycine, alanine, and phenyl alanine was measured at different temperatures using atomic absorption spectrophotometer. It was found that, the rate of cementation decreases with increasing the percentage of composition of amino acids and increases by increasing temperature and the number of rotation. Thermodynamic parameters ΔH*, ΔG* and ΔS* were calculated.
