When the standard free energy of the coil-to-globule transition is treated as a function of salt concentration, it monotonically decreases for more repulsive ions with little affinity to the polymer. A different behavior is observed for the attractive ions: After an initial depression caused by the screening and bridging effects at low salt concentrations, the function rises because the swelling by attraction mechanism is introduced at high salt concentration. However, in the case of highly charged polymer chain (ξ = 0.10), the screening-bridging mechanism dominates in the whole investigated concentration range (up to 2 m). Thus the salting-out power of ions is reversed when compared to the uncharged polymer.
