Construction of a New Aluminum(III) Cation Selective Electrode Based on 12-Crown-4 as an Ionophore

Use of Dicloxacillin Al(III) Complex as a Modifier for Determination of Al(III) Ion in Real Samples

“…The performances of the three proposed Al(III) electrodes were compared with the previously reported ones [21, 22, 28, 29, 48–52]. As shown in Table 3, the coated paste electrode showed superior response to the target cation ions over the other proposed sensors because of the wide linear range, short response time and Nernstian slope.…”

Exploitation of bis(tert‐butylaminomethyl)pyridine as a chemical modifier in a carbon paste electrode for sensitive and selective potentiometric determination of Al3+ ion in pharmaceutical and water samples

“…Over the past few decades, a variety of organic and inorganic materials have been behaved as ionophores in the literature for the selective detection of Al 3 + ions. Al 3 + selective ion carriers have included thioureas [2], anthraquinones [26], zeolites [27], Schiff base derivatives [28][29][30], imidazoles [31], flavonols [32], crown ethers [33], and salicylidenes [1,34,35]. However, many of these reported electrodes have drawbacks like a constrained pH working range, short shelf time, low sensitivity, slow response, and considerable other metal ions interfering.…”
