This volume presents the solubility of inorganic compounds of actinides except for
carbonates, which are included in Volume 74 of this series, and nitrates, which are
covered in Volume 55. Also included are solubility data of compounds such as organo-
sulfates, phosphates, and arsenates, which are not covered in Volume 74. The predomi-
nant part of this volume covers solubility data of thorium, uranium, neptunium, and
plutonium compounds. Fewer data have been published for americium compounds and
very few for compounds of actinium, protactinium, and transamericium elements. The
literature has been covered up to the end of 2004. Documents which remained unavail-
able to the editor, and could not be included in the volume are listed in the Appendix. For
some compounds it was not possible to show the Chemical Abstracts registry numbers
since these have not been assigned. © 2007 American Institute of Physics.
