activated carbon (AC) were studied with Pb2+, Fe2+, Ni2+, and Cu2+ solutions selected as
components of the target wastewater. The physical and chemical properties of the surface of
modified AC were monitored by scanning electron microscopy, elemental analysis, and
automatic surface area and pore size analysis. The adsorbance of metal ions was measured
by inductively coupled plasma optical emission spectrometry. The adsorbance of Fe2+ and …
