In addition to natural pollution, the environment is also affected by anthropogenic pollution, which has increased more and more with the development of industry and the excessive use of natural resources. A significant form of environmental pollution is heavy metal pollution. The most important sources of heavy metal pollution of the aquatic environment can be the discharge of domestic and industrial wastewater, agriculture and industrial processes. One way of removing heavy metals from wastewater is the application of adsorption processes using efficient adsorbents that are relatively easy to find, in large quantities and at a low price. These adsorbents can come from by-products obtained from industrial processes, such as slag resulting from the production of pig iron and steel. In this work, the use of blast furnace slag was followed to observe its ability to adsorb heavy metals from wastewater. The use of slag in the removal of heavy metals is a challenge and a way to research because there are multiple studies that provide evidence that slag can be used in wastewater treatment.
