Rezumat

Purpose: Establishing of the adsorption processes particularities of Candida albicans fungus on activated carbon obtained from aprikot husks. The activated carbons used have a specific BET area of about 1500 m2/g and a total sorption volume of the pores being in the range of 0,95-1,08 cm3/g. The experimental results of the kinetics of the adsorption processes were registered at 15, 30, 45…150 min of the contact. In order to carry out the research of the fungus adsorption on the mentioned activated carbons, solution of this fungus with an optical density of 0,52 was prepared. This density was recorded at the КФК-2-УХЛ photo colorimeter 4,2. At the beginning of the experiment 5, 10, 15… .50 ml of the prepared fungal solutions were placed in 10 flasks, to which 45, 40, 35,… 5 ml of distilled water were added to dilute the initial prepared solutions. Subsequently, it was established the calibration curve. The prepared solutions were then contacted with pre-weighed activated carbon samples, approximately 100 mg each. After 90-150 min of contact, the optical densities were measured at a wavelength of 315 nm, and then subsequently calculated the equilibrium concentrations and the adsorption values. The kinetics of the adsorption of the studied fungus showed that the value of the maximum adsorption is established within 2,5 hours. At the 90-150 min contact times the adsorption values were in the range of 0,9-1,12 McF*108/g. Because the diameter of the studied fungus is between 2000-4000 nm, we can conclude that the adsorption of the fungus will take place in the macropores of carbonic adsorbent.
