Sorption properties of selected sorbents suitable to remove Platinum group cytostatics from hospital waste water and from model solutions of selected Pt group cytostatics were evaluated. Suitable sorbents – Clinoptilolite, Bentonite (from Braňany, Czech Republic), Lufa and Supersorbon were selected for testing the Platinum cytostatics removal by the process of sorption from contaminated waste water. Supersorbon activated coal and Bentonite (Braňany) were evaluated as efficient sorbents suitable for all tested Pt cytostatics, which probably relates to their structure – the largest volume of pores, porosity and specific surface area. During testing it was found that Platinum compounds precipitate out of the solutions, while this was insignificant only in the Carboplatin solution. This reached up to 85 % in several tests with Cisplatin and Oxali-platin solutions. It was shown that this phenomena occur even in case of the real hospital waste water.
