  ABSTRACT: The construction and performance characteristics of a novel Iron(III) membrane sensor based on (37-bis-[(diethoxy-thiophosphoryl)-oxy]-5,11,17,23,29,35-hexa-kis-(1,1-dimethylethyl)-calix[6]-arene-38,39,40,41,42-pentol) (A) were reported in this paper. The sensor was prepared by incorporating compound (A) into a plasticized polyvinyl chloride PVC membrane. The electrode reveals a Nernstian behavior over a wide iron ion concentration range (1.0 × 10-2 - 1.0 × 10-4 mol·L-1), and relatively low detection limit (1.0 × 10-5 mol·L-1). The potentiometric response was independent on the pH of the solution in the range of 4 - 7. The electrode showed a very short response time (
