Release of Aluminum, Arsenic, Cadmium, Chromium, Copper, Iron, Lead, and Zinc in a Coal Leachate, and their Removal from Solution Undergoing Neutralization
Whole coal contains significant amounts of iron pyrite which is oxidized ultimately to ferric acid sulfate. As a result, trace elements are released from the coal and other minerals in potentially hazardous concentrations. ...
CHROMIUM OXIDATION AND REDUCTION BY HYDROGEN PEROXIDE IN DIVERSE SOILS AND SIMPLE AQUEOUS SYSTEMS
Hydrogen peroxide is being tested for in situ remediation of buried contaminants - either as a direct chemical oxidant in Fenton-type reactions or as a source of oxidizing equivalents in bioremediation. How it affects a ...
Investigation of the Tetrahymena Pyriformis 2-Aminoethylphosphonic Acid Biosynthetic Pathway and the P-C Bond Forming Enzyme Phosphoenolpyruvate Mutase
The biosynthetic pathway leading to 2-aminoethylphosphonate in Tetrahymena pyriformis was determined. A cell-free homogenate of T. pyriformis converted phosphoenolpyruvate to AEP in 37% yield, phosphonopyruvate to AEP ...
Transition Metal Polypnictides from Zintl Ions
The chemistry of the soluble E7 3- ions (E = P, As, Sb) with various transition metal complexes has been investigated. Alloys of K3E7 react with (arene)M(CO)3 (M = Cr, Mo, W) complexes in the presence of three equivalents ...
