The effect of 1-decanol on the potentiometric response of three ion-selective electrodes to large cationic species is analyzed. The electrodes were constructed with plasticized PVC membranes. The results suggest that 1-decanol alters the ionic transp

The surface properties of poly(mono‐n‐alkylmaleate‐alt‐N‐vinyl‐2‐pyrrolidone) sodium salts derivatives with n=8, 10, 12, 16, and 18 carbon atoms in the side chain were analyzed. The surface tension behavior suggests that the adsorption

The influence of decyl alcohol on the potentiometric response of three para-alkylbenzenesulfonate (p-RBS) electrodes is analyzed. The results are clearly dependent on the membrane surface polarity due to the presence of the alcohol. The ionophore was

The interfacial properties of poly(maleic acid-alt-1-alkene) disodium salts at hydrocarbon/water interfaces are determined. In all the studied systems, the interfacial tension decreases markedly with the polyelectrolyte concentration as the side-chai

The surface properties of poly( N -monoalkylmaleamic acid-alt-styrene) sodium salts are studied as a function of the molecular weight and the size of the linear alkyl lateral chain of the polyelectrolyte. The experimental results are well described b

The effect of phenols containing different electron-withdrawing substituents on the potentiometric responses of several liquid PVC membranes containing the complex trioctylmethylammonium–nitrate, TOMA+NO3−, is analyzed. The results make it possib

An isopropyl xanthate ion-selective electrode was constructed using as a carrier the complex trioctylmethylammonium-isopropyl xanthate. Two kinds of plastic membranes were built, with dioctyl phthalate (DOA) and dioctyl adipate as plasticizers. In bo

A new, rapid, and simple method for preparing long-chain alkyltrimethylammonium (A1TA+X−) or long-chain alkylpyridinium (A1Py+X−) salts (X− = F−, Cl−, Br−, NO3−, SO42−, PO42−, car☐ylic anions, etc.) is presented. The method is bas
