Whether it is a single dye or a mixed dye, the decolorization rate of SG-APT-DDF remains above 95% in the range of pH=4-10; the effect of inorganic salt on the decolorization performance of SG-APT-DDF adsorbent is from large to small. It is PO43->CO32->SO42->NO32->Cl-. As the concentration of inorganic salt increases, the decolorization efficiency of the adsorbent decreases.
