A nanocomposite based on carbon paste electrode fabricated, by using zeolite as ion carrier .Functional multi-wall carbon nanotube was used for improvement of electrode response. The optimal composition of CPE was built from 65% graphite powder, 20 wt% paraffin oil, 5% ion carrier (zeolite), 10% MWCNTs. Electrode showed Nernstian response 19.88 (±0.2)mVdecade "1 in the measuring range 10 "7 -10 "2 mol L "1 and showed detection limit of 6.3×10 -7 M. The sensor was successfully used for potentiometric titration Cr 3+ with EDTA. The carbon paste electrode showed fast response time, good selectivity and applicable in the wide pH range of 3 -10.

This review presents a general overview about the development of ion-selective electrodes in Iran during the past decade (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). All of the reported ion-selective sensors (for cations, anions and organic species) are cited in this review. Sensors for 39 cations, 12 anions, and 23 organic compounds and drugs have been reported in this reivew. Some of the main group cations (e.g. beryllium) as well as most of the lanthanide ion (i.e., presidium, erbium, lutetium, cerium, neodymium, europium, gadolinium, terbium, dysprosium, holmium, ytterbium, and thulium) sensors have been reported for the first time. It is noticable that the best reported sensors for HPO 4 2-, SO 4 2-, Cl -, ClO 4 -, Br -, and I 3 -have been designed and constructed by the Iranian researchers.

In this work, we introduce a highly selective and sensitive silver(I) PVC-membrane sensor. Dilaktam Crown ether (DLCE) was used as a membrane-active component to prepare a highly sensitive Ag(I)-selective polymeric membrane electrode. This sensor illustrated very good selectivity and sensitivity towards silver ions over a wide variety of cations, including alkali, alkaline earth, transition and heavy metal ions. The sensor exhibited a Nernstian behavior (with a slope of 59.8 ± 0.2 mV per decade) for a concentration range (1.0 × 10 -5__ 1.0 × 10 -1 M) with a detection limit of 6.8×10 -6 M. It displayed a response time in the whole concentration range (~20 s) and its usage exceeded a 75 days period in the pH range of 5.1-7.2. The proposed electrode application was found to be successful as an indicator electrode in the titration with NaCl.
