Graphical Abstract: At a given supersaturation state, the conventional affinity-based rate law predicts a rate that is independent of the ion ratio (green horizontal line). However, the ion activity ratio influences the instantaneous rate, changes in the rate over time, and the nature of precipitation kinetics at extreme ion ratios. Log of strontium distribution coefficient as a function of calcium carbonate precipitation rate; our study compared to other similar previous studies (Lorens [13]; Tesoriero & Pankow [16]; Nehrke et al. [20]; and Tang et al. [21]). Lines shown for each respective data set represent linear fits of the data. DSr Data from Lorens [13] are calculated based on the best fit line equation (LogDSr = 0.249*LogR-1.57) of the experimental data used.
