EFFECT OF SIZE AND CHARGE ON ORDERING OF A HIGHLY-CHARGED CONCENTRATED MACROIONS IN SUSPENSION

An efficient fast Fourier transform method has been employed to determ ine correlation function [g(r)] using the structure factor [S(Q*)] ca lculated with the rescaled mean spherical approximation (RMSA) and the DLVO potential. Based on this function a parametric (size and charge) study of the ordering in a highly charged and concentrated macroions (an ideal colloid) has been made. The strength of the correlation incr eases with the increase in the charge on macroions and it saturates af ter a certain value. Similarly, a critical diameter of the particle de pending on the charge on it has been found at which normal feature of the ordering disappears.
