The principles involved in the design of enterohepatic chelating agents, which facilitate the biliary rather than the renal excretion of toxic metal ions are outlined. The syntheses of some novel chelating agents designed to exhibit such behavior are presented. The basic features exploited in the ...
Some examples of chelating agents are ethylenediaminetetraacetic acid/edetic acid (EDTA), sodium edetate (Na-EDTA), disodium edetate (2Na-EDTA), dipotassium edetate (2K-EDTA), calcium disodium edetate (2NaCa-EDTA), trisodium edetate (3Na-EDTA), diethylenetriaminepentaacetic acid/pentetic acid (DTPA...
The chelating agents falling within the generic structure I are illustrated in Table 2 below:TABLE 2 Examples of chelating agents having generic structure I Entry Structure 1a 1b 1c 1d 1e 1f 1g The term “idealized structure” is used herein to designate the structure indicated and additional ...
Examples of agents used include bathophenanthroline disulfonate and ferrozine. The resulting complex leads to color changes that are dependent on the concentration of the complex and the optical characteristics of the agent used. These changes are proportional to ambient iron concentrations. Both manual ...
