“…Inductively coupled plasma mass spectrometry has arisen as one of the preferred methods due to its unique combination of low detection limits, capabilities for rapid multi-elemental and isotopic determination and wide dynamic range [23]. Despite the significant improvements on solid sample introduction techniques such as laser ablation sampling [29] or slurry sampling electrothermal vaporization [30][31][32][33][34], solution nebulization is still the most preferred method for many ICP-MS applications [35].…”

A method for simultaneous multi-element analysis of fly ash samples by inductively coupled plasma orthogonal acceleration time-of-flight mass spectrometry (oaTOF-ICP-MS) after closedvessel microwave extraction with ammonium fluoride was introduced here. Corrosive and and/or toxic acids like HF, HCl or HClO 4 , as well as HNO 3 , which are commonly used during sample preparation of the fly ash samples are avoided in this method. The spectral effects due to the formation of different Cl, Na, K, Ca, Mg, containing polyatomic species interfering the determination of number of elements like As, Se or Ni during the oaTOF-ICP-MS analysis are negligible. Under the optimum experimental extraction conditions evaluated using a fractional factorial design being 10 mg of the sample extracted with 5 mL of 140 g L −1 NH 4 F for 10 min at 200 °C, subsequent analysis of the resulting supernatant enabled under optimum instrumental conditions and with Rh as an internal standard precise and accurate simultaneous determination 2 of 11 elements (Li, Be, Ni, As, Se, Rb, Sb, Cs, W, Tl and U) at trace and ultra-trace levels. The accuracy was assessed by analysing two certified reference materials, namely Fine Fly Ash CTA-FFA-1 and Constituent Elements in Coal Fly Ash Standard Reference Material ® 1633b. The precision of the reported method was better than 10 %.

Coal fly ash contains several trace elements some of which are toxic such as As, Cr, Pb, etc. Coal ash also contains relatively high amounts of rare earth elements whose recovery from coal ash could be an alternate source for their supply. Although uranium and thorium are less chemically toxic than other constituent elements such as arsenic, questions have been raised concerning the possible risk from radiation. Hence, the concentration levels of all of these trace toxic elements in fly ash samples have to be assessed to determine whether the ash is hazardous or not, and also to decide the place and method of its disposal or reutilization. In this study, multielemental analysis of some coal ash samples originating from two thermal power plants in southern India has been carried out, employing inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS), with the focus on some trace toxic elements. The methods employed were validated by analayzing international certified fly ash reference materials. The concentrations of trace-toxic elements in the samples analyzed were: 20-82 µg/g for As, 45-281 µg/g for Cr, 31-607 µg/g for Ba, 21-865 µg/g for Sr, 8-39 µg/g for Ge, <5-80 µg/g for Ga, <5-100 µg/g for Cu, 19-50 µg/g for Co, 58-258 µg/g for Ni, 8-73 µg/g for Pb, 44-260 µg/g for Zn, 0.6-8.6 µg/g for U, 1-30 µg/g for Th, 6-196 µg/g for La, 14-528 µg/g for Ce, 5-196 µg/g for Y. These results were compared with trace-toxic element concentrations in coal ash samples as reported in the literature.
