Water pollution is an increasingly troublesome problem, water being a precious, renewable, but limited resource, and an essential factor in maintaining life on the earth. With the increasing population number, the strong and uncontrolled industrialization, and the aggressive behaviour of the population, relative to environmental protection, more and more toxic residues and substances have been released into the environment, jeopardizing its balance. The treatment of water contaminated with heavy metal ions is a real challenge, due to the fact that the costs of applying the current treatment technologies are very high, with low efficiency. Due to the high toxicity of heavy metals, the serious effects they have on the abiotic factor, but also the toxic effects and illnesses they cause to living organisms, researchers have focused their attention on the implementation of new effective solutions in order to eliminate these toxic pollutants. This paper aims to highlight a less conventional method used for treating water contaminated with heavy metal ions. The process is based on the ability of the Typha angustifolia L. to metabolize the heavy metal ions present in the water, and it also has the advantage of recovering the metal from the plant, at the end of its growth process. The paper wanted to highlight an efficient method, which implementation and functioning does not harm the environment. Taking into account the promising results of the experiments and the low costs involved in using this method of treating wastewater contaminated with heavy metal, it is desirable to implement it or to use it on a large scale. Studies will also be continued within a research project from the National Research Plan, in order to observe the plant’s effectiveness in adsorbing other types of heavy metals.
