Abstract
Crown ethers have often been reported as potential ionophores in alkal i ion-selective electrodes. Several new lipophilic lariat crown ethers possessing a variety of single and double side alkyl arm(s) were foun d to act as lead-selective neutral carriers in liquid membrane electro des. Lead was detected as a monovalent permeating species of the type PbOH+. The obtained analytically relevant lead sensors show a high sel ectivity with regards to other heavy metal ions, low detection limits ranging between 10(-6) and 10(-7) mol/l and short response times.
