The net adsorption, W, of non-boundary states at interfaces in two-dimensional Potts models is studied using Monte Carlo techniques. For the three-and four-state Potts model the net adsorption is found to diverge when the critical point is approached as W∼t-ω, where t=(Tc-T)/T. Finite-size effects have been also studied; for an N x N lattice the net adsorption at the bulk critical temperature behaves as Wc∼Na. The numerical results for the exponents ω and a are consistent with a scaling argument that yields ω=ν-β and a=1-(β/ν).
