Abstract
The possibility of synthetic silicone sorbent PSTU-3F using 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 was investigated. It was shown that the amount of adsorption is the higher, the higher the acidity of the solution. It has been established that the mercury adsorption process on the PSTU-3F sorbent is described by the Freundlich equation.
