Metal Leaching of Fly Ash from Municipal Waste

Biological leaching of fly ash from municipal waste incineration by Aspergillus niger was examined in batch cultures and compared with chemical leaching. A. niger grew in the presence of up to 10% (w/v) of fly ash in the medium. In the presence of fly ash A. niger produced gluconate, whereas in its absence citrate was produced. Variation of the fly ash concentration in the growth medium (one

Suitability of leaching test methods for fly ash and slag

Oct 01, 2015· Numerous leaching studies of coal fly ash have demonstrated that the quantity of major and trace elements extracted can be extremely variable, depending on the nature of both the fly ash and the leaching solution (Brubaker et al., 2013; Van Der Sloot et al., 2011., Valerie, 2007). It is difficult for a new researcher to identify the suitable

THE EXAMINATION OF HEAVY METALS LEACHING FROM FLY ASH

The fly ash can escape when molecules expand because larger cracks and crevices are made because the expanding water breaks apart the concrete. The 50% fly ash samples generally had more leaching of metals than the 30% sample or the 0%. Conclusion: Hypothesis 1is accepted because heavy metals did leach out of the concrete samples.
