“…The Epsilon 3 energy dispersive X-ray fluorescence (XRF) analyzer from PANalytical (Almelo, Netherlands) was used to record the XRF data. The GL-SPE vacuum manifold kit from GL Sciences (Tokyo, Japan) in combination with the CAS-1 air pump from AS ONE (Osaka, Japan) was used during SPE Journal of Hazardous Materials, 254-255: [10][11][12][13][14][15][16][17]2013 The original publication is available at: http://dx.doi.org/10.1016/j.jhazmat.2013.03.028 treatment. The Navi F-52 pH meter from Horiba Instruments (Kyoto, Japan) and a combination electrode was used for pH measurements.…”

“…It should be noted that the commercial-scale application of the chelant-assisted solid waste treatment process is by far limited mostly due to the higher cost of reagents [17,32].…”

“…EDTA, the most acclaimed aminopolycarboxylate chelants (APCs), has been used for the selective backextraction of indium from an anion-exchange resin during the process of indium separation Journal of Hazardous Materials, 254-255: [10][11][12][13][14][15][16][17]2013 The original publication is available at: http://dx.doi.org/10.1016/j.jhazmat. 2013.03.028 from the spent catalysts [16].…”

“…2013.03.028 from the spent catalysts [16]. However, APCs have rarely been used to treat any vitrified waste [10] in spite of being praised for excellent metal-binding capacities and extensive use in the treatment of contaminated soil solids [17][18][19][20]. Hence, the current report is an effort to comprehend the potential of APCs for indium extraction from the ITO-film composed to a dense vitrified structure.…”
