“…Addition of surface active compounds (surfactants) can prevent the attachment of bacterial cells to the sulfur-containing minerals. Thomson and Turney (1996) described the possible treatment of pyrite using various fatty acid amines, resulting in a substantial reduction of the bioleaching process. Sasaki (1997) demonstrated a possible use of oxalic, tannic and fulvic acids to prevent bacterial attachment with the best results achieved with fulvic compounds.…”

Environmental Technologies to Treat Sulphur Pollution: Principles and Engineering

In the environment, different types of solid phase systems can contain high concentrations of inorganic sulfurous compounds, e.g. ores, soils and sediments. The key criterion in the assessment of environmental risks of inorganic sulfurous compounds present in these materials is whether they remain bound to the solid phase or whether they are mobilized into the solution. Mobility of inorganic sulfur in natural water/solid biphasic systems is predominantly controlled by oxidative or reductive changes and precipitation constants of sulfurous compounds. In anaerobic environments, sulfur is encountered in its most reduced form, i.e. sulfidic form. Owing to the poor solubility of most sulfidic compounds, sulfurous compounds are predominantly immobile in anaerobic environments. On the contrary, in aerobic environments, the most stable inorganic sulfur compound is sulfate, which is usually very soluble in water. Reductive and oxidative changes of inorganic sulfurous compounds often involve an interaction with protons. Sulfur reduction is usually accompanied with alkalization of the environment, whereas sulfur oxidation often results in acidification. The general overview of the effects of reductive and oxidative

Contamination of soil and groundwater by trinitrotoluene (TNT) is a persistent and widespread problem confronting existing and former military bases and ammunition manufacturing facilities throughout the United States and the world. TNT-contaminated water has been generated by a number of means. The manufacture of TNT generates large quantities of wastewater, which is contaminated with TNT and other products. TNTcontaminated groundwater is found at many sites. Leachate systems have also been used to remediate TNT-contaminated soil, and these systems generate wastewaters that must be treated.Cost-effective treatment of TNT-contaminated water is an important issue. Existing technologies include:
