Se—Cd coordination number as a function of elapsed time determined by EXAFS independently for the Se—P and Se—Cd pairs (open squares and open circles, respectively) compared with the value determined by the XANES fit (closed circles). The dashed line indicates the Se—Cd coordination limit. The reacted amount of Se and Cd during the reaction is assumed to be equal. As the initial [Se] and [Cd] concentrations are 30 mM and 12 mM, respectively, the upper limit of the reaction yield is [Cd]0/[Se]0 = 40%. |
