Polyamine Type IEF’s Adsorption Efficiency to Cyanide and Copper

The adsorption capacity of two kinds of Ion exchange fiber (IEF) was compared to treat the wastewater contained CNT and Cu, then adsorption efficiency of Poly Acrylo-amidino Triethylene tetramine Fiber (PATAF) was studied under different pH (7.5-9.0) and flow rate (80.4-160.8 BV⋅h-1). The concentration of cyanide and complex ion were measured at pH=8, flow rate=126.0 BV⋅h-1, and the desorption conditions were studied under different concentration and flow rate.
