【Abstract】 The sluminosilicate salt active intermediate is synthesized by heating coal fly ash with sodium hydroxide and hydrolysis, studying on cation and anion organic dyes decolourization conditions. The samples are characterized by FTIR and XRD patterns. By Uv_vis absorption spectrum the results show that the active intermediate has a better decolourization effect for cation and anion organic dyes.更多还原
