The Sorption of Platinum Group Cytostatics of Hospital Wastewater

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 (Branany, Czech Republic), Lufa and Supersorbon were selected for testing of Platinum cytostatics removal by the process of sorption from contaminated waste water. Supersorbon activated coal and Bentonite (Branany) 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 for the Carboplatin solution. This reached up to 85 % in several tests with Cisplatin and Oxaliplatin solutions. It was shown that this phenomena occurs also in case of the real hospital waste water.
