Is there any reliable source where I can get the surface tension coefficients of binary mixtures containing water?
The surface tension of water is decreased by CO2 and levels off at higher pressure. The determination of interfacial tension in these systems is, however, not so easy to measure and there may be discrepancies between different experiments. There are references to relevant literature in these articles:

This second paper gives some data which the authors have selected as being the most reliable.
Is there any generalized formula using which we could calculate the surface tension of binary mixtures containing water? I am simulating the problem of a bubble rising in ANSYS. Hence, I need the surface tension coefficients for different mixtures.
Dennis is right. Most experiments are done in pressure cells. There is no generalized formula or empirical relation to calculate IFT of binary mixtures with one species being water. Here is a literature that lists quite a few binary mixtures of H2O (see Table 1). I hope this helps.
