Reaction Steps
Four hundred fifty μl of 100mM solutions of each of chromic chloride, ferric chloride, manganese chloride and dysprosium chloride were mixed with 50 μl of 1M 1,4,7-triscarboxymethyl-1,4,7,10tetraazacyclododecane and adjusted to pH 4.5. The solutions were heated at 88° C. for 20 minutes to enhance the rate of chelation, cooled and then adjusted to pH 7.
