“…Biopolymer (alginate, carrageenan, pectin)-LDH nanocomposites have also been used in PISE devices for calcium determination [17]. A synthetic Friedel's salt was used in a carbon paste for the accumulation of iodite species and their subsequent voltammetric determination [18]. A ZnAl-LDH/Au modified electrode was applied to detect iodate in real samples, such as iodized salt [19].…”

From an exhaustive overview based on applicative academic literature and patent domain, the relevance of Layered Double Hydroxide (LDHs) as electrode materials for electrochemical detection of organic molecules having environmental or health impact and energy storage is evaluated. Specifically the focus is driven on their application as supercapacitor, alkaline or lithium battery and (bio)-sensor. Inherent to the high versatility of their chemical composition, charge density, anion exchange capability, LDH-based materials are extensively studied and their performances for such applications are reported. Indeed the analytical characteristics (sensitivity and detection limit) of LDH-based electrodes are scrutinized, and their specific capacity or capacitance as electrode battery or supercapacitor materials, are detailed.

“…5 LDHs have been used for electrode modification due to their large specific surface, good adsorption and ion-exchange ability, and stable chemical property in electrochemical reactions. [6][7][8][9] Notably, these materials exhibit great potential as anion exchangers. In the LDH structure, the partial substitution of divalent metal ions by trivalent ones induces positive charges on the layers, while solvated anions between layers can neutralize these positive charges.…”

Simple and rapid determination of iodide in table salt by stripping potentiometry at a carbon-paste electrode

et al. 2002

A simple and rapid procedure, utilising constant-current stripping analysis (CCSA) at a carbon-paste electrode containing tricresyl phosphate as a pasting liquid (TCP-CPE), has been developed for the determination of iodide in table salt. Because of a synergistic accumulation mechanism based on ion-pairing and extraction of iodide in combination with electrolytic pretreatment of the TCP-CPE, the method is selective for iodide and enables direct determination of iodide in samples of table salt containing anti-caking agents such as K(4)[Fe(CN)(6)] (food additive "E 536") or MgO. The iodide content (calculated as KI) can be determined in a concentration range of 2 to 100 mg kg(-1) salt, with a detection limit (S/N=3) of 1 mg kg(-1), and a recovery from 90 to 115%. The proposed method has been used to determine iodide in several types of artificially iodised table salt and in one sample of natural sea salt. The results obtained agreed well with those obtained by use of three independent reference methods (titration, spectrophotometry, and ICP-MS) used to validate the CCSA method, indicating that the developed method is applicable as a routine procedure for rapid testing in salt production process control and in the analysis of marketed table salts.
