Schulz distribution function and the polydispersity of the binary suspension of charged macroions

Bidispersity of binary suspensions of charged macroions due to different sizes and charges are reduced into one-component model (OCM) using Schulz distribution function. Ordering in charged macroions has been studied using rescaled mean spherical approximation (RMSA) method with modified Derjaguin, Landau, Verwey and Overbeek (DLVO) potential. The results obtained are compared with the experiment, weight-average and Roger–Young (RY) schemes. It is inferred that Schulz distribution function is a plausible model to average out size and charges of macroions to study the structural behavior of the binary suspension of macroions. An ordering with co-ordination number 12 has been reported in the binary suspension of charged macroions.
