   Sammanfattning : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. LÄS MER

3. 2. Phosphorus recovery from sewage sludge fluidized bed gasification processes

   Författare :Thomas Karl Hannl; Marcus Öhman; Matthias Kuba; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; sewage sludge; agricultural residues; bed material; fluidized bed; feldspar; ash transformation; potassium; phosphorus; ICP-AES MS; SEM; EDS; XRD; thermodynamic equilibrium modeling; Energy Engineering; Energiteknik;

   Sammanfattning : One of the most sustainable pathways of sewage sludge treatment in recent years has been thermal conversion. The benefits of thermal treatment of sewage sludge are the recovery of energy or valuable chemical products, the destruction of harmful organic compounds, the separation of heavy metals from the P-rich coarse ash fraction, and the decreased and sanitized ash volume.

5. 4. Characterization of suspended particulate matter from freshwater : validation of a field filtration technique

   Författare :Fredrik Ödman; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Sammanfattning : A field filtration method for the concentration and separation of suspended particulate matter (SPM) from freshwater systems and the subsequent determination of major, minor, trace and ultra trace elements (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, Hf, K, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, S, Sb, Sc, Si, Sn, Sr, Ta, Th, Ti, Tl, U, V, W, Zn and Zr) is validated with respect to detection limits, precision, and bias. The validation comprises the whole procedure including filtration, sample digestion and instrumental analysis. LÄS MER

7. 5. Coupled Liquid Separation and Spectrometric Detection of Organic Compounds Containing Hetero-atoms

   Författare :Eva Nilsson; Jean Pettersson; Karin Markides; Joanna Szpunar; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : This thesis exemplifies the strength in the combination of inductively coupled plasma (ICP) spectrometry and electrospray ionization tandem mass spectrometry ESI-MS/MS as detection techniques for liquid chromatography (LC) in the search for and investigation of compounds that bind or can bind hetero-atoms. Furthermore, some aspects involved in the coupling of LC and ICP spectrometry and quantification without identical standards have been studied. LÄS MER
