Promethazine determination in plasma samples by using carbon paste electrode modified with molecularly imprinted polymer (MIP): Coupling of extraction, preconcentration and electrochemical determination

Amperometric determination of promethazine in tablets using an electrochemically reduced graphene oxide modified electrode

“…12 There are different electrode surfaces which have already been used as detectors for phenothiazine derivative detection, such as the boron-doped diamond, 13 the nanodiamond modified with Ag particles, 14 gold, 15,16 carbon nanotubes, [17][18][19] glassy carbon, 20 FTO modified with SiPy + Cl À and CuTsPc film, 21 and modified carbon paste electrodes. 22,23 To the best of our knowledge, the amperometric detection of promethazine hydrochloride using a rGO modified sensor is reported here for the first time.…”

Determination of trace formaldehyde in blood plasma by resonance fluorescence technology

“…In order to assess the effects of foreign substances on the RFS procedure described above, the selectivity of this assay was studied by analyzing synthetic sample solutions containing 0.10 g mL −1 of HCHO, where a series of other ions and organics had been added according to the likely interference composition in human blood plasma samples [33]. The experiment results demonstrated that 500 times of K + , Na + , Cl − and citric acid, 100 times of Zn 2+ , Al 3+ , Ba 2+ , HPO 3 2− , SO 4 2− , HCO 3 − and Mg 2+ , benzoic acid, 50 times of I − , Fe 3+ , Cu 2+ , glucose and phenol, 40 times of acetaldehyde, benzaldehyde and human serum albumin, 10 times of cresol, acetoacetate, acetone, naphthol, resorcinol and pyrocatechol.…”

Preparation of nano-sized Pb2+ imprinted polymer and its application as the chemical interface of an electrochemical sensor for toxic lead determination in different real samples

“…We have recently reported several papers describing the application of MIP particles as a recognition element of the electrochemical sensors such as voltammetric and potentiometric sensors for different kinds of molecular analytes [80][81][82][83]. In this study, a lead imprinted polymer, as an ion recognition material, was synthesized by a new formulation.…”
