Stability test study on incinerator fly ash treated by hydroxamic acid
|
Abstract:
Based on component analysis of incinerator fly ash and leaching toxicity test of fly ash,LH2 was used as chelating agent to stabilize heavy metals in the incinerator fly ash.The results indicated that,fly ash was dominated by oxides of Si,Ca,Al,Fe,S,K,Na and Mg which showed a certain toxicity;LH2 could be used as the agent for treating heavy metal ions in fly ash,which could meet the requirements of leaching heavy metal ions for hygiene landfill and co-treatment with municipal wastes at a dosage amount of 2...
