A potentiometric iron sensor based on the use 3-(2-diethylamino-ethylimino)-1,3-dihydro-indol-2-one (DEDIO) as an ionophore in poly(vinyl chloride) (PVC) matrix, is reported. The plasticized membrane sensor exhibits a Nernstian response for Fe(III) ions over a wide concentration range (2.0 × 10-6-5.0 × 10-2 M) with a super Nernstian slope of 26 ±1 mV per decade. It has a fast response time of <12 s and can be used for ten weeks without any considerable divergences in its potentials. The electrode can be used in the pH range 4.5-8.0. The proposed sensor shows fairly good discriminating ability towards Fe(III) in comparison with a large number of alkali, alk. earth, transition, and heavy metal ions. The sensor was used as indicator electrode in potentiometric titration of Fe(III) vs. EDTA. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Synthetic Route of C12H22O4).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Synthetic Route of C12H22O4
