<![CDATA[The analysis of changes in levels of copper (Cu) on the addition of silver ions (Ag) with electrocoagulation method has been researched by using Atomic Absorption Spectrophotometer (AAS) as an instrument for the determination of levels. The addition of ionic silver (Ag) in a solution of copper (Cu) using varying concentrations of silver (Ag) 4, 6, 8, 10 and 12 ppm. The results showed that the effect of the addition of ionic silver (Ag) 4,6, 8, 10 and 12 resulted in changes in the levels of copper (Cu) are deposited successively in the ppm concentration is 9.375; 9.324; 9.272; 9.168; 9.142 and 9.116.
