Abstract

Cefazolin is an antibiotic used in the treatment of bacterial infections. In the present study, the synthesis of polyaniline-polyethylene glycol resin modified with the surfactant methylhexyl imidazolium hexafluorophosphate and its performance in removing cefazolin were examined by the surface adsorption process. The contact time of 60 minutes of adsorbent and cefazolin was selected as the optimal time due to high removal efficiency. Due to the high removal efficiency of cefazolin at pH = 5 due was selected as the optimal pH. The adsorbent with the value of m=3 g was selected as the optimal adsorbent. The results revealed that with increasing the concentration of cefazolin, the removal efficiency decreased from 69% to 50%. The results of testing showed that the percentage of removal of cefazolin in distilled water decreased from 98.46% to 72.72% in urban water. The results of adsorbent reduction showed that the removal percentage of cefazolin decreased from 93.99 to 74.55% after 6 steps by nitric acid and decreased from 41.25 to 21.56% by NaOH. According to these results, it can be stated that this resin has a high capability to remove the antibiotic cefazolin from aqueous media.
