Contact angle and surface tension in the celestite plus sodium oleate aqueous solutions plus air system
The contact angles of the ternary system celestite + sodium oleate aqueous solutions + air were measured in the range 7.3 x 10(-6) mol.L-1 and 6.2 x 10(-4) mol.L-1 of sodium oleate at pH between 4 and 12 and at the temperature 20 degreesC. The surface tensions of the aqueous solutions of sodium oleate were also measured to obtain the values of the work of adhesion at the solid-liquid interface.
