Efficient Adsorption of NH4+ Ions on Modified Fly Ash/EPDM Environmentally Friendly Composite
In our study, a new kind of NH4+ sewage water treatment composite was prepared by melt blending, with synthetic rubber EPDM as the matrix, modified fly ash as the filler. The removal rate of NH4+ increased with increasing pH (The range of pH investigated was 2.0-5.0.), the removal rate of NH4+ decreased with increasing pH (The range of pH investigated was 5.0-9.0.); increasing temperature made against the adsorption, “Room temperature” is the optimum temperature; the removal rate of NH4+ increased with increasing adsorption composite content. When the adsorption reached equilibrium, the removal rate was remain unchanged.
