TLDR
In this paper, the weathered residues retrieved after fly ash leaching were analyzed for major constituents by atomic absorption spectrophotometry and trace elements by instrumental neutron activation analysis, and the characteristics of the residues ranged from highly leached acidified material, from which many constituent elements had been mobilized, to minimally leached alkaline material containing accumulations of newly formed secondary minerals.About:

Leaching behaviour of elements from coal combustion fly ash: An overview
Maria Izquierdo,Xavier Querol +1 more
TL;DR: In this paper, the authors provide an extensive look at the extent to which major and trace elements are leached from coal fly ash and give an insight into the factors underlying the leachability of elements and addresses the causes of the mobility.

Arsenic hazards in coal fly ash and its fate in Indian scenario
TL;DR: In this paper, a review on the concentration of As in FA, its fate and behaviour as hazardous element on human health, environment quality and on mitigation strategies to accomplish environmental management is presented.
Journal ArticleDOI
Mobility of trace elements from coal and combustion wastes
TL;DR: In this paper, the mobility of > 30 trace elements from four Spanish coals was investigated using sequential extraction procedures, and the total leachable fractions were obtained by comparing the total trace element content in the bulk coal samples with the extractable content.
Journal ArticleDOI
Leachability of elements from sub-bituminous coal fly ash from India.
TL;DR: It was found that Cd, Co, Cr and Ni did not leach from the ash while Cu and Pb concentrations were insignificant in the leachate regardless of liquid to solid (L/S) ratio.
Journal ArticleDOI
Leachability and adverse effects of coal fly ash: A review
TL;DR: The basic physico-chemical properties of CFA are introduced, followed by a systematic summary and discussion of the leachability of C FA via different leaching methods and the chemical speciation of some typical metal elements in CFA, which is related to its harmful effects.

Trace elements in fly ash: dependence of concentration on particle size
TL;DR: In this article, the concentration of 25 elements in fly ash emitted from a coal-fired power plant were measured as a function of particle size using spark source mass spectroscopy, optical emission spectrography, atomic absorption spectrum analysis (AASSA), and x-ray fluorescence analysis.
