In the paper "Conditionally exactly soluble class of quantum potentials" byA. de Souza Dutra [Phys. Rev. A 47 (1993) R2435] the whole $s-$wave spectrum ofbound states in potentials $V_1(r)=A/r+B/r^{1/2}+G_0/r^2$ with$G_0=-3\hbar/32\mu$ and $V_2(r)=A r^{2/3}+B/r^{2/3}+g_0/r^2$ with$g_0=-5\hbar^2/72\mu$ has been constructed in closed form. We show that boththe result and the method of its derivation are not correct.Comment: extended and published versio
