Inorganic Concentrations in Selected Woods and Charcoals Measured Using NAA
Keywords:Inorganics, woods, charcoals, NAA, southern pine, earlywood, latewood
AbstractNeutron activation analysis was used to determine the levels of several inorganic elements in seven species of wood- and laboratory-prepared charcoals. The samples were exposed for 1 min to a thermal neutron flux of 1 x 1014 n/cm2-sec. Following a 10-min decay period, sample activity was measured for 500 sec. Concentrations of Al, Ca, Cl, K, Mg, Mn, and Na were measured. Ba, Cu, Sr, and V were also identified in several samples. Matched samples of southern pine earlywood and latewood contained similar amounts of inorganics.
