Fabrication of Pb2+ ion selective electrode based on 1-((3-((2-hydroxynaphthalen-1-yl)methyleneamino)-2,2-dimethylpropylimino) methyl) naphthalen-2-ol as new neutral ionophore was written by Ghaedi, M.;Montazerozohori, M.;Andikaey, Z.;Shokrollahi, A.;Khodadoust, S.;Behfar, M.;Sharifi, S.. And the article was included in International Journal of Electrochemical Science in 2011.Electric Literature of C12H22O4 This article mentions the following:
The potentiometric study of complexation of 1-((3-((2-hydroxynaphthalen-1-yl)methyleneamino)-2,2-dimethylpropylimino)Me) naphthalen-2-ol (HMDMN) show strong interaction between HMDMN and Pb2+ ion while their formation constant was evaluated using potentiometric data. The suitability of the HMDMN for construction of new Pb2+ ion PVC membrane electrode and its potentiometric determination was studied. The influence of variables including pH, membrane ingredients was optimized and set as PVC:DBP:carrier:NaTPB:NaTPB/carrier mole ratio with the percent mass ratio of 28.9:57.8:8.0:5.33:0.83. At optimum values of all variables the electrode response is linear in the concentration range of 1.0 鑴?10-6 to 0.1M with detection limit 4.0 鑴?10-7 M with Nernstian slop of 25.79 mV/decade over the pH range of 5.0-7.2. This electrode with appropriate response time 閳?0s and suitable reproducibility (relative standard deviation), can be used for at least 2 mo without any measurable divergence in response properties. The proposed sensor reveals good selectivity toward Pb2+ ion with respect to many alkali, alk. earth, transition and heavy metal ions. It was applied to the determination of Pb2+ in water and soil samples. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Electric Literature of C12H22O4).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Electric Literature of C12H22O4
