Determinação do ponto de névoa em surfactantes não iônicos por espectroscopia de impedância elétrica
Química Nova, 2010 In this paper, we analyze the use of electrical impedance spectroscopy applied to determination of cloud point. The slope of admittance measured at 100 kHz is reduced to temperature above the critical value which characterizes the phase transition, in a ...
