Fariba Mehranfar; Arezoo Ghaemi; Haman Tavakkoli

Volume 6, Issue 1 , Spring 2016, Pages 41-49

Abstract
  A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6to 1.0×10-1M, with a Nernstian slope of 18.0±1.0 ...  Read More
