Abstract

In the latest years, there is an increase of an interest for cleaning industrial polluted waters containing heavy metals, which threatens the human health and pollutes the environment as well. A high amount of toxic metals in industrial polluted waters are shed in the environment in several forms. The metallurgic processes are producing a high amount of solid and liquid waste that are dumped into the water and in this way creates significant harmful effects for the environment and human health. It is known that heavy metals such as manganese, iron, nickel, chrome, arsenic, cadmium, cobalt, uranium, copper, etc. are very toxic elements, therefore, by dumping them into waters they will pollute the environment as well as living beings directly through the food chain. The critical toxicity of heavy metals has caused several disasters in the environment in the human history, so there is a fear of a catastrophic pollution nowadays, therefore new methods for treatment are required which do not have side effects. Biosorption is a special method of extraction and elimination of heavy metals from polluted waters and the same is done with natural wastes which are relatively cheap and easily approachable (biomass), these are food waste and the phyto-pharmaceutical waste. Vegetative waste from extraction of Herba Hypericum can be used as a biomass in order to eliminate completely or to reduce extremely toxic metals from the polluted water, especially chrome, cobalt and nickel that are considered as highly toxic metals which are very difficult to extract compared with other methods. This kind of treatment of metallic polarities is of a great importance for developing countries, in economic aspects and the aspect of accomplishing strict criteria of green technology.
