Formation of iron minerals on zeolite matrix

We present results of a two-year research experiment on the processes involving iron-manganese bacteria at different biogeochemical barriers. Analysis of experimental samples was carried out on a scanning electron microscope (EVO-40HV, Carl Zeiss) and an X-ray diffractometer (Rigaku MiniFlexll). It is shown that goethite can form in vitro in the presence of iron-containing groundwater and iron-manganese bacteria.
