The
adsorption of the tetrammincopper (II) complex on activated carbon (AC) from the
water solution was investigated. The spectrophotogram of the solution with the
constant Cu2+ ions content and the increasing NH4OH
content showed that a stable complex is obtained when the molarity ratio of the
given ions is
. The maximum absorbance wavelength is 600-605 nm, and the absorbance is a
linear function of the complex concentration. The adsorption of [Cu(NH3)4]2+
ions on activated carbon has been confirmed by the reduction of the
complex solution absorbance after its contact with AC, and the quantity
of.
