Abstract

It is well known if the amount of heavy metals in liquid waste is higher than allowed, there is a potential danger for the health of humans and other living organisms. They can also cause different troubles in technological processes. That is why monitoring
and controlling the content of heavy metals in liquid waste of industrial system is very important.
Furthermore, foundries also have great difficulties with the disposal of their harmful waste material. Safe disposal of hazardous waste and substances is a task equally important as maintaining quality and profit. The aim must be to reduce the amount of waste
through regeneration or some other applications.
The purpose of this paper was to examine adsorption of Cr (VI) ions from water solution on the non-toxic foundry waste material. The results showed that foundry waste material can be used for adsorption of Cr (VI) ions.
