Abstract
The possibility of using the PSTC-3F synthetic organosilicone sorbent for the adsorption removal of mercury from an aqueous solution has been studied. The dependence of mercury adsorption on the pH of the solution, the amount of the adsorbent and the duration of the contact of the solution with the adsorbent is examined. It is shown that the higher the solution acidity is, the higher the adsorption value is. It has been established that the mercury adsorption process on the PSTC-3F sorbent is described by the Freundlich equation.
