A novel resin NKZ, which is a macroporous resin intermediate modified with nitroguanidine, was synthesized and identified. The adsorption behavior of five kinds of water-soluble dyes onto the resin NKZ was investigated thermodynamically in detail. The results showed that the adsorption rate for reactive brilliant blue KN-R is higher than those for the other dyes. The equilibrium data can be well-described by a three-parameter equation. The values of ΔG° demonstrate that the first layer adsorption of the dyes onto NKZ involves both physical ad...
