Bacterial generation of liquid arsenic waste and the application of water-soluble polymers for arsenic ions separation

Abstract

Two aspects of the bio-geo-chemical arsenic cycle in the environment are analysed. The bioleaching and chemical weathering of selected arsenic bearing minerals are presented. The natural bacteria adaption to the higher concentration of arsenic ions is described. The secondary precipitation of minerals containing arsenic was discussed regarding the immobilisation of arsenic ions in soil. Water-soluble polymers are combined with membranes to remove arsenic species under different experimental conditions. © 2014 The Author(s).
