The adsorbed leaching liquor was analyzed by atomic emission spectroscopy and colorimetric method. The contents of various kinds of ions in ACFF were determined with X-ray photoctron spectroscopy. ACFF not only adsorbed gold but also adsorbed arsenic, nickel, zinc, calcium, sulphur, bismuth, copper, iron, silver and cyanide anion. Atomic percentage of C and those of O, N, Zn, Fe increase and decrease respectively with the increase of the layer depth, while those of Ca, Au, Ag keep constant.展开更多
