A new mercury solid-state ion-selective electrode has been prepared by directly coating the surface of a platinum disk electrode with THF (THF) solution containing poly(vinyl chloride) (PVC), 1,2-bis(quinolin-8-ylsulfanylmethyl)benzene (BQSB), dioctyl phthalate (DOP) and potassium tetrakis(p-chlorophenyl)borate (KTpClPB). The electrode exhibits a Nerstian response in the range of 1.0 × 10-7-1.0 × 10-2 M with a detection limit and slope of 8.0 × 10-8 M and 29.7 ± 0.3 mV/decade resp. The response time to achieve a 95% steady potential for Hg2+ concentration ranging from 1 × 10-5 to 1 × 10-2 M is ∼15 s, and the electrode is suitable for use within the pH range of 1.7-4.0. The proposed electrode revealed fairly good discrimination ability towards Hg+2 in comparison to some alkali, alk. earth, transition and heavy metal ions. Applications of this electrode for the determination of mercury in environmental waters, and as an indicator electrode for potentiometric titration of Hg+2 ions with iodide, were reported. It could be applied for the determination of mercury in environmental waters. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Category: esters-buliding-blocks).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Category: esters-buliding-blocks
