Abstract (EN)
In this study, adsorption of Ethidium bromide on to Potamogeton crispus and Enteromorpha spp. was studied. Effect of pH on adsorption was determined and optimum adsorption was observed at pH 3 for both adsorbent. Effect of temperature were determined at 20, 30 and 40°C. The increasing of the temperature increased of the adsorption capacity of EtBr. The maximum adsorption capacity of the Potamogeton crispus was determined as 0.21, 0.215 and 0.235mMg-1 and 0.195, 0.224 and 0.246mMg-1 for Enteromorpha spp. Langmuir adsorption isotherm modelling is the fit experimental results. Equilibrium adsorption time was determines as 70 and 50 min for P. crispus and Enteromorpha spp. respectively.Pseudo-second order kinetic modelling and intraparticle diffusion kinetic modelling was suitable for description of the adsorption mechanisms. This result shows that adsorption mechanisms controlled by complex mechanisms. Key Words: Ethidium bromide, Adsorption, Potamogeton crispus, Enteromorpha spp., Kinetic modelling
