oktan oktadecyloaminy - Opis:
- he usability of the micellar enhanced ultrafiltration (MEUF) for removal of phosphates from aqueous solutions has been evaluated. The process was performed with the use of polyethersulfone membranes under various transmembrane pressures (0.1, 0.15, and 0.2 MPa). Phosphorous solutions containing 15 mg of PO3-4/dm3 and two cationic surfactants: octadecylamine acetate (ODA) and hexadecylpyridium chloride (CPC) were used in the tests. The concentration of ODA and CPC amounted to 2 and 3 CMC (Critical Micelle Concentration) as well as 2, 3 and 6 CMC, respectively. The results of the study showed that the surfactant type and its concentration influenced the process efficiency. The phosphate removal with the use of ODA was approximately 95%, whereas application of CPC gave unsatisfactory results.
