Versuchsvorschrift

50mM Bismuth(III) (1,4,7-triscarboxymethyl-1,4,7,10-tetraazacyclododecane) was prepared by combining 24.2 mg of bismuth nitrate with 100μl of 1M 1,4,7-triscarboxymethyl-1,4,7,10-tetraazacyclododecane and 140 μl of acid. The solution was adjusted to pH 3 with dilute sodium hydroxide. The mixture was heated at 88° C. until the bismuth nitrate dissolved (ca. 30 minutes). The solution was adjusted to pH 7.3 with dilute sodium hydroxide and reheated briefly at 88° C. until a small quantity of precipitate was dissolved. On cooling, the solution remained clear.
