Cobalt(II)-selective membrane electrode based on a recently synthesized benzo-substituted macrocyclic diamide.
A PVC-membrane electrode based on a recently synthesized 18-membered macrocyclic diamide is presented. The electrode reveals a Nernstian potentiometric response for Co2+ over a wide concentration range (2.0 x 10(-6)-1.0 x 10(-2) M). The electrode has a response time of about 10 s and can be used for at least 2 months without any divergence. The proposed sensor revealed very good selectivities f...
متن کاملPotassium-Selective Membrane Sensor Based on Two Recently Synthesized Poly(oxyethylene) Derivatives
Two poly(oxyethylene) derivatives 1.10-bis(2'-benzoic acid)-1,4,7,1-tetradecane (L1) and 1,7-bis(2'-benzoic acid)-1,4,7-trioxaheptane (L2) were used as suitable ionophores for the preparation of potassium-selective PVC-membrane electrodes. The resulting electrodes based on L1 and L2 exhibit linear responses to the activity of K+ ions within the concentration ranges of 3.1<em...
متن کاملHighly Selective Perchlorate Membrane Electrode Based on Synthesized Schiff Base Complex
In this work we introduce a practical use of synthesized Schiff base metal complex in sensing application. A new perchlorate-selective electrode based on the complex N, N'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (II) [CuL] as the membrane carrier was developed. The electrode exhibits a good Nernstian slope of -55.0 ± 1.0 mV/decade and a linear range of for perchlorate. The lim...
