Undersøkelse vedrørende utvasking av tungmetaller fra impregneringsslam

Abstract

Det er utført forsøk for å klarlegge i hvilken grad vann kan løse ut arsen, kobber og krom fra slam som dannes ved trykkimpregnering av trevirke. Arsen og kobber ble langsomt løst ut, men ikke krom. Ut fra forsøkene er det beregnet at fra 1 kg slam vil 14,1 g arsen og 4 g kobber kunne lutes ut, og dette utgjør henholdsvis 45 og 57% av de respektive metallene i slammet. Innstøping av slam i en blanding av sand, Portlandsement og kalk reduserte utlutingen i meget stor grad
