A method aimed at poten charged ionophores in ion surements of segmented s of ion association requires ment of the sandwichmu ionophore complexationm evaluated. Association of Experimental results are with commonly used sites bis[4-(1,1,3,3-tetramethyl
متن کاملIon-Selective Carbon Paste Electrode Based on 2-Amino-N-benzthioazolyl Benzamide (ABTB) for Determination of Copper (II) by Potentiometric Method
2-Amino-N-benzthioazolyl benzamide (ABTB) was synthesized, characterized and used for thefabrication of a potentiometric sensor for Cu2+ metal ions. The electrode exhibits linear response to Cu(II) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 M) with Nernstian slope of 30 ± 1.5 mVper decade. The electrode can be used in the pH range from 2 to 9. It has a fast response time of about1...
متن کاملComparison of the vanadyl-selective electrodes prepared by sol–gel and PVC membrane techniques
Sol-gel and polymeric membrane electrodes, based on thiacalix[4]arene as a neutral carrier, weresuccessfully developed for the detection of VO2+ in aqueous solutions. The sol-gel and PVCmembrane electrodes exhibited linear response with Nernstian slopes of 29.3 and 28.4 mV perdecade, respectively, within the vanadyl ion concentration ranges from 1.0 × 10-6 to 1.0 × 10-1mol dm-3 and from 1.0 × 1...
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 کاملLinearity and stability of the AVL and Nova magnesium and calcium ion-selective electrodes.
We studied the stability and linearity of the AVL and Nova Mg and Ca ion-selective electrodes and the relation between the ionized Ca and ionized Mg results reported by each analyzer. The response of the electrodes to different concentrations of Mg and Ca was determined for saline solutions, aqueous solutions, and serum samples. The electrodes from both manufacturers demonstrated acceptable sta...
