Abstract
On request of the National Energy Administration a study to clarify the leaching of the metals arsenic, cadmium, copper, mercury, molybdenum, and zinc has been carried out. The investigated material have been fly ash from coal and wood separate, mixed together and mixed with sludge of bark. The study was also planned to show or indicate the pH-value at which the leaching of the above-mentioned metals increase. The investigations show that the leaching from both the clean ashes and the mixtures of ash and sludge of bark is fairly low, but that the leaching is partly higher for the mixture compared with the clean ashes. This means that at the disposal site, mixture with organic waste ought to be avoided. Instead the two types of waste can be disposed in layers, which will reduce the leaching in comparison with the achieved results during the leaching tests. 24 figs., 17 tabs.
