Using the electromigration method the monopositive astatine ion has been shown to form EDTA [H4L] complexes in 0.1M NaClO4 solution at pH=3–10. The ion mobility of the AtL3− complex is 5.60/23/x10−4 cm2.V−1.s−1.

Characterization of DTPA complexes and conjugated antibodies of astatine

The conjugation procedure for the production of At-DTPA conjugated polyclonal antibodies is described and the complexes formed were investigated by electromigration in free electrolytes and by gel-chromatography on Sephadex G 25.

Production of [(211)At]-astatinated radiopharmaceuticals and applications in targeted α-particle therapy.

Several compounds have shown high potential for the treatment of cancers in vitro and in several animal models, thus providing a promising basis that has allowed initiation of the first two clinical studies of astatine-biomolecule bond.

Determination of ion mobilities by IBM PC controlled nuclear electromigratic method

An IBM PC controlled nuclear electromigratic measuring system was developed to determine ion mobilities of different radioactive isotopes. The software and interface are shown in detail.



Chemical properties of positive singly charged astatine ion in aqueous solution

AbstractThe mobility of oxidized astatine in solutions H(Na)ClO4 (μ=0.4 M) − 1·10−4M K2Cr2O7 has been measured at 25°C in the interval 0.63≤pH≤1.68. Under these conditions astatine migrates to the

Determination of ion mobilities of radionuclides in a free electrolyte. Methods and experimental organization

A new variant of a technique for determining ion mobilities by means of horizontal zone electrophoresis in free solutions is developed. Setup circuit is presented. Some details of experiment and
