Structural Formation and Leaching Behavior of Mechanically Activated Lignite Fly Ash Based Geopolymer

Abstract: Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation.… Show more

“…The peaks between 1430 and 1410 cm -1 indicate the stretching vibration of the O-C-O bond of atmospheric carbonation, due to the reaction of NaOH with atmospheric CO 2 . Between 1090 and 990 cm -1 the peaks assigned to the asymmetric stretching vibrations of Si-O-Si and Si-O-Al bonds can be found, which are characteristic to geopolymers [2,4,12,13,14].…”

“…The technique to analyse the leachate is not specified by any of the abovementioned leaching procedures, but a variety of methods can be applied, such as atomic adsorption spectrophotometry, inductively coupled plasma atomic (optical) emission spectroscopy (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS) or laser induced breakdown spectroscopy [1,13,16].…”

“…The infrared spectrum (Figure 1 (c)) shows the main absorptions occurred at 460, 594, 795, 1104 and 1455 cm -1 . The two spectrum bands at 594 and 795 cm -1 are attributed to Si-O-Si symmetric stretching vibrations (quartz phase) (Ciocinta et al, 2012;Mucsi et al, 2016). The two main spectral bands at 460 and 1104 cm -1 are attributed to Si-O-Si and O-Si-O bending, and Si-O-Si and Al-O-Si asymmetric stretching, respectively (Álvarez-Ayuso et al, 2008).…”
