Abstract :
Studying on the eluting and adsorpting the saturated ANJ.SiC by different regenerants, NaOH is the most suitable one. The influence of the factors containing NaOH concentration, elution time and regeneration times on ANJ.SiC regeneration rate was studied. The results show that the best NaOH concentration is 0.5mol/L, with the regeneration rate of 115.83%; the best elution time is 60min, with the regeneration rate of 113.52%; after the second recycling, the highest regeneration rate is 106.49%. Also the mechanism of ANJ.SiC regenerated by NaOH is preliminary studied, which mainly contains: dredged channel, oscillation opening and changing on the surface chemical properties of ANJ.SiC.
