Application of zeolites for radium removal from mine water.

Chałupnik S, Franus W, Wysocka M, Gzyl G - Environ Sci Pollut Res Int (2013)

Bottom Line: We found that technique as a very promising method for removal of not only radium isotopes from mine waters but also other ions (barium, iron, manganese).Preliminary results show very good effects for radium isotopes as well as for barium ions.In the paper, a short description of laboratory results of the purification of mine waters with application of synthetic zeolites is presented.

ABSTRACT
For removal of radium from saline waters in Upper Silesian mines, several methods of purification have been developed. The most efficient one is based on application of barium chloride, which was implemented in full technical scale in two Polish coal mines several years ago. Very good results of purification have been achieved-the removal efficiency exceeding 95% of the initial activity. Another possibility for the removal of different ions from salty waters and brines is the application of zeolites. We found that technique as a very promising method for removal of not only radium isotopes from mine waters but also other ions (barium, iron, manganese). Treatment of several various water samples has been done to assess the removal efficiency for natural radionuclides. Preliminary results show very good effects for radium isotopes as well as for barium ions. In the paper, a short description of laboratory results of the purification of mine waters with application of synthetic zeolites is presented.

Fig1: Location of Upper Silesian Coal Basin

Mentions: The Upper Silesian Coal Basin (USCB) is located in the southwestern part of Poland (Fig. 1). Presently, Silesian underground coal mines extract about 90 million tons of coal per year. The depth of mine workings is from 350 to 1,100 m. The geological structure of the Upper Silesian Coal Basin is very complicated and differentiated with numerous faults and other tectonic dislocations. The mining activity is causing destruction of the strata, leading to the increase of permeability. Two hydrological regions of the Coal Basin are recognized. The first region is located in southern and western Silesia, where there are thick strata of sediments covering carboniferous formation. The cover of up to 700 m is built mainly by Miocene clays and silts. Such strata restrict migration of water and gases. In the second region located in the northern and eastern part, Miocene deposits do not occur. Carboniferous strata are covered either by slightly compacted Quaternary sediments or numerous outcrops of coal seams. The oldest formations of this area comprise strongly fissured and isolated sediments of Permian or Triassic limestone. These formations enable very easy migration of water and gases (Różkowski 1978).Fig. 1
