A significant amount was lost while capping the reactor due to the <br /> nearly instantaneous and vigorous reaction upon addition of reagents. <br /> * * Because the reaction was so vigorous that not all of the off-gases could be collected, the % Volatilized is too low. <br /> PRIMA Environmental, Inc. 13 Eval of Peroxide <br /> February 8, 2007 Cambria-G Street, Davis <br />
