21. Efficient Adsorption of NH4+ Ions on Modified Fly Ash/EPDM Environmentally Friendly Composite

Author

Liu, Xiu Qi and Xing, He Qin

Abstract

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.

22. Study of Roasting Fe2O3/EPDM to Remove Crude Oil in Water

Author

Liu, Xiu Qi and Xing, He Qin

Abstract

In our study, a new kind of material for oil adsorption was prepared by melt blending with EPDM as the matrix and roasting Fe2O3 as the filler. The effects of dicumylperoxide (DCP) and roasting Fe2O3 contents on the oil absorbency were studied. The results show that the oil absorbency reaches the highest value for the roasting Fe2O3/EPDM composite with 2 wt % DCP and 30 wt % roasting Fe2O3. Comparing the oil absorbency for three samples, the experimental result indicates that the oil absorbency of roasting Fe2O3/EPDM composite is higher than that of EPDM (crosslinked) and EPDM.

23. Preparation and Cr6+ Adsorption Property of Zeolite/EPDM Composite

Author

Liu, Xiu Qi and Xing, He Qin

Abstract

In our study, a new kind of material for Cr6+ absorbency was prepared by melt blending with EPDM as the matrix and modified zeolite as the filler. Contrast between natural zeolite, acid modified zeolite and modified zeolite / EPDM composite on equilibrium adsorption amount (Q), the results showed that the Q of composite were far greater than that of natural zeolite and acid modified zeolite.

24. Crude Oil Adsorption on Fe2O3/EPDM Composite to the outside Environmental Variations

Author

Liu, Xiu Qi and Xing, He Qin

Abstract

In our study, a new kind of material for oil adsorption was prepared by melt blending with EPDM as the matrix and roasting Fe2O3 as the filler. By considering the influence of pH, temperature, stirring speed on adsorption capacity. The results showed that the environmental pH has little effect on the crude oil absorbency of the composite; “Room temperature” is the optimum temperature; increased the stirring speed can reduce the adsorption time.
