Critical coagulation concentration (CCC) is the minimum salt concentration required to trigger coagulation of macro-ions in a solution. Mo-132, the macro-ion with -42 charges, exhibit anomalous lower CCC value for monovalent counter-cations in comparison to divalent cations. Researchers from Akron University and University of Chicago have recently measured the distribution of monovalent (Rb+) and divalent (Sr2+) cations surrounding Mo-132 clusters using Anomalous Small Angle X-ray Scattering (ASAXS). The radial distribution of the ions surrounding the Mo-132 clusters obtained from ASAXS analysis reveals stronger affinity of the monovalent ions (Rb+) in comparison to the divalent ions (Sr2+).
