Lead-selective poly(vinyl chloride) electrodes based on some synthesized benzo-substituted macrocyclic diamides

Selective and sensitive lead (II) solid-contact potentiometric sensor based on naphthalene-sulfonamide derivative

“…Many efforts have been made to construct Pb(II) ISEs by using different organic and inorganic compounds (Srivastava et al 1995;Jain et al 2006, Chen et al 2006, Soleymanpour et al 2012Wardak 2011;Elmosallamy et al 2008;Li et al 2009;Michalska et al 2009;Kazemi et al 2009;Wilson et al 2010;Abbaspour et al 2010;Huang et al 2011;Zamani et al 2011;Yin et al 2012;Lisak et al 2012;Guzinski et al 2013). Very recently, the Rong et al (2012) reviewed the Pb(II) ISEs based on ionophores bearing oxygen/sulfur functional groups.…”

Lead(II)-Selective Coated Graphite Electrode Based on Benzo-18-crown-6

“…The selectivity behaviour is obviously one of the most important characteristics of an ion-selective electrode, determining whether a reliable measurement in the target sample is possible. To investigate the selectivity of the membrane electrode proposed, its potential response was investigated in the presence of various interfering foreign cations using the mixed solution method [23][24][25][26] . The potential measured in solutions containing a fixed amount of Pb 2+ ion (1.0 × 10 -3 mol L -1 ) 7.4 × 10 -4 Fe 2+ 3.9 × 10 -4 Cu 2+ 9.6 × 10 -4 Zn 2+…”

A new potentiometric thiosalicylamide-functionalized polysiloxane carbon paste electrode for lead(II) determination

“…For these advantages, ISEs found various applications: in clinical chemistry, environmental protection, water, soil, etc., and analytical chemistry in general [6]. PVC membranes, coated wires and chemically modified carbon paste electrodes (CMCPEs) have been successfully applied as potentiometric sensors for determination of lead [7][8][9][10][11][12][13][14][15][16][17][18][19].…”
