Abstract

This research aimed to evaluate the efficiency of sap method in penetration and retention of commercial Osmose CCB preservative in Prosopis juliflora (Sw) D.C. round pieces and to investigate appropriated times and concentrations to wood treatment. The pieces were submitted to 1; 2 and 3% of CCB solutions during 3, 6, 9, 12 and 15 days. The penetration of copper and boron elements were analyzed in disks taken in 5 positions in pieces, as well as the retention in 3 positions (ground contact area, middle and top of pieces). In this work was observed a better penetration and retention of CCB in wood exposed to 2% CCB solution. The element boron presented a satisfactory penetration in all positions, concentrations and analyzed times. In function of copper and boron penetrations and CCB retention, the submitted pieces to 2% CCB solution, during 15 days, are able to ground contact uses.
