fosfaatitulppaus
Fosfaatitulppaus, also known as phosphate capping or phosphate sealing, is a process used in some industrial applications to reduce the leachability of heavy metals from solid waste materials. This method involves adding phosphate-containing compounds, such as calcium phosphate or iron phosphate, to the waste. These compounds react with the heavy metal ions present in the waste, forming less soluble and more stable phosphate compounds.
The primary goal of fosfaatitulppaus is to immobilize hazardous metals like lead, cadmium, and arsenic, preventing
While fosfaatitulppaus can significantly reduce the mobility of heavy metals, it is not always a permanent
