Resumo
Energy dispersive (EDXRF) and Portable (PXRF)
X-ray fluorescence techniques are proposed for wood treatment
control process and wood waste assortment. In this
study, different retentions of chromated copper arsenate
preservative were applied to Eucalyptus sp. sapwood samples.
Cu, Cr and As were determined by XRF techniques in
treated sapwood massive blocks and treated sapwood sawdust
samples were analyzed by FAAS spectrometry (Flame
Atomic Absorption) and INAA (Instrumental Neutron
Activation Analysis). Cu, Cr and As mean values, obtained
by FAASS and INAA, showed to be statically equal; however,
XRF analysis showed considerable deviations, presenting
the absorption and the enhancement effects in
analytical lines.
