rjs.silva Posted May 25, 2006 Share Posted May 25, 2006 Hi! I'm a student from Portugal, and I have a problem on measuring the surface tension of a solid... in order to measure this tension, I have done the du Nouy ring method and measured the contact angles for diferent concentrations of a solution of tensioactive... I have ploted the angles Vs Concentration and for the Du Nouy i have ploted the surface tension Vs Concentration.... ( I have calculated the CMC for the two cases) Now my problem is how to use this data in order to calculate the surface tension of the solid...
