Abstract: |
|
This paper investigated the removal efficiency of five trace pharmaceuticals, including carbamazepine(CBZ), ketoprofen (KEP), naproxene (NAP), diclofenac (DCF) and acetaminophen (ACE), which were detected frequently in aquatic environment, by reverse osmosis (RO), nanofiltration (NF) and membrane distillation (MD). The results show that RO and MD can remove these five selected drugs efficiently. During MD process, none of these pharmaceuticals was detected in the permeate; CBZ, KEP, NAP and DCF by RO process were not detected in the permeate neither,which were almost completely removed. The removal efficiency of ACE was slightly lower, but it was also up to 96.5 %. However, NF process had lower efficiency than MD and RO processes for removing drugs. The removal efficiency of KEP, NAP, DCF and ACE were 60.5±0.5%, 82.3±0.7%, 84.2±0.4%, 83.5±1%, 41.1±0.2% respectively. |
