Inorganic pollutants include (a) cationic heavy metals such as lead, cadmium, and nickel, (b) anionic metals and inorganics such as arsenic, chromium, selenium, nitrate and fluoride, and (c) radionuclides such as strontium and uranium. The geochemistry of these pollutants can widely vary and it depends on the specific pollutant type and soil/sediment properties. The speciation and transport of these pollutants also depend on the dynamic changes in the pH and redox potential of the soil that occurs under applied electric potential. The dominant transport process...

This book is a general survey of the nature of trace metals in petroleum and includes analytical methods for their determination. Vanadium, iron, nickel, cadmium, copper, and molybdenum— their nature, determination, chemical aspects, geochemistry, occurrence in new and used petroleum byproducts and their recovery for resource use—are dealt with in detail by the expert authors in this volume. Among the methods covered are instrumental analysis, neutron activation, activation analysis, oxidative demetallation and kinetic studies. Includes 54 figures and 60 tables.
