Abstract:

Iron and manganese oxide /activated carbon composite (GACF1M3) was prepared and the experiment conditions including pH ,GACF1M3 dosage and organic effect were evaluated in the H2O2 decomposition. The results showed that the decomposition of H2O2 increased with time ,GACF1M3 can decompose H2O2 about 75% in 120min . The amount of H2O2 reflected the maximum usage rate of the GACF1M3 when the dose was 100mg. The highest H2O2 decomposition of GACF1M3 was achieved at pH 8.5, the maximum OH· production was pH 5.0.The presence of HA can increase H2O2 decomposition while TCP has the opposite effect.
