Particle electrophoretic mobility measurements were used to determined ξ potentials of uric acid as a function of concentration for various ionic species found in human urine. Uric acid ξ potentials are qualitatively described as a function of solution pH in a synthetic urine. A theoretical model is proposed to describe the mechanism of uric acid surface-charge formation in terms of the monoprotic surface group model of T. W. Healy and L. R. White [Adv. Colloid Interface Sci., 9, 393 (1978)].
