Bacterial Reduction Of Barium Sulphate By Sulphate-Reducing Bacteria

Bacterial Reduction Of Barium Sulphate By Sulphate-Reducing Bacteria Abstract Acid mine drainage (AMD) is a worldwide problem leading to contamination of water sources. AMD are characterized by low pH and high content of heavy metals and sulphates. The barium salts application presents one of the methods for the sulphates removing from AMD. Barium chloride, barium hydroxide and barium sulphide are used for the sulphates precipitation in the form of barium sulphate. Because of high investment costs of barium salts, barium sulphide is recycled from barium sulphate precipitates. It can be recycled by thermic or bacterial reduction of barium sulphate. The aim of our study was to verify experimentally the possibility of the bacterial transformation of BaSO 4 to BaS by sulphate-reducing bacteria. Applied BaSO 4 came from experiments of sulphates removal from Smolnik AMD using BaCl 2 . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nova Biotechnologica et Chimica de Gruyter

Abstract

Abstract Acid mine drainage (AMD) is a worldwide problem leading to contamination of water sources. AMD are characterized by low pH and high content of heavy metals and sulphates. The barium salts application presents one of the methods for the sulphates removing from AMD. Barium chloride, barium hydroxide and barium sulphide are used for the sulphates precipitation in the form of barium sulphate. Because of high investment costs of barium salts, barium sulphide is recycled from barium sulphate precipitates. It can be recycled by thermic or bacterial reduction of barium sulphate. The aim of our study was to verify experimentally the possibility of the bacterial transformation of BaSO 4 to BaS by sulphate-reducing bacteria. Applied BaSO 4 came from experiments of sulphates removal from Smolnik AMD using BaCl 2 .
