Solid waste from the red ceramic industry (chamotte clay) was assessed as glycerol adsorbent for biodiesel purification by dry washing. Its structure and composition was analyzed by several techniques, such as X-ray diffraction, FT-IR, scanning electron microscopy and particle size. By using a simulated medium (5w/v% glycerol in an ethanol solution), a face centered composite design was used to analyze...
This study examined soil physico-chemical properties, P fractions, and P sorption–desorption at two depths (0–3 and 3–6cm) after a wildfire in a Pinus pinaster stand in north-central Portugal. Depending on fire severity, soils from three sites were considered for this study: long-unburned (US), low crown consumption (LCC) and high crown consumption (HCC). The fraction of fines (0–3 and 3–6cm), total...
