#### Abstract

A dynamic growth of the industry related to the development of technology and the growth of consumption are the main causes of pollution in the natural environment. The control of the amount of air, soil and water pollution as well as performing different types of decontamination processes on a large scale have become necessary along with the growing awareness of the dangers resulting from the current conditions. In practice, there are many applied decontamination in situ and ex situ technologies, each suitable for a particular medium and contamination. The choice of a method depends on the location of the polluted soil, air or water, the type of the pollution, its concentration and the further purpose of the purified medium. In this paper, the method of groundwater remediation with the use of permeable reactive barriers was investigated. Laboratory research was aimed at the comparison of the usefulness of different types of sorption materials used for heavy metals removal in permeable reactive barriers. Zinc (Zn) was chosen as a typical heavy metal due to the fact that it is an element of a very high degree of potential threat for the environment. That is because zinc has the ability to spread easily. Two methods, static and dynamic, were chosen for the zinc sorption examination. The following sorbents were used to compare their effectiveness in a series of laboratory tests: synthetic (3AS, 4AP, 5A and 13X), fly ash and natural sorbent: diatomite. Based on the acquired values of partitioning coefficients it may be concluded that the abovementioned sorbents present satisfying affinity of zinc in the contaminated solution. The larges¬t measured values of partitioning coefficients were obtained for diatomite, 4AP and 13X. The acquired results of the element equilibrium concentrations indicate a non- linear II or IV isotherms type due to the Brunauer’s classification. Another key fact is that the time of reaching the equilibrium state in the static method is insignificant and its approximate value is 4 hours. The results confirm the possibility of using the above mentioned sorbents for zinc immobilization on permeable reactive barriers. The dynamic method proved to be decisive (of the two methods used) to confirm the results.
