The generalized indirect Fourier transformation (GIFT) method allows the simultaneous fitting of P(q) and S(q) by selecting a suitable S(q) model. The monodispersed charged sphere S(q) model with the Yukawa potential and the Hypernetted chain (HNC) closure was used to account for potential inter-particle scattering effects in this work. For the effective charge, the zeta potential was used to approximate the surface potential ψp in the following equation (Eq. 3), where the charge of the sphere with radius a is calculated. 58
