Dear gmx users
I would like to calculate the number of the surfactant molecules adsorbed on the
nanotube surface as a function of time. I would be pleased if anyone could tell 
me
whether there is a program in gromacs to do that or not?

Not directly, but perhaps you can integrate an RDF if designed cleverly. Otherwise, you'll have to script calls to g_dist or g_mindist with whatever adsorption criteria you have established for each molecule and count the frames in which the criteria are satisfied.
