“…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.…”

However, the steric hindrance between DTPA and dissolved metals might play an important role in the mixed matrix solution.…”

“…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].…”

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].…”
