The study of electrochemical behavior of aluminum-cupferron complex indicated that aluminum and cupferron formed complex in 0.4 mol/L (NH 4)2SO4 solution. Accumulation potential of -0.95 V (vs. SCE) was applied, while the solution was stirred for 60 s. The response curve was recorded by scanning the potential to the negative direction and the peak current of -1.18 V (vs. SCE) was recorded. This complex absorbed in hanging mercury drop electrode (HMDE) and create a sensitive peak current. The peak current and concentration of aluminum accorded w...
