“…On the other hand, FI and multicommutation methods 15,16 have been described for the determination of a single carbamate pesticide. LODs obtained were, in general, similar to those provided by the present work, although in the optimization process they studied a single pesticide only, whereas in our HPLC-PICL method optimal conditions were established for eight pesticides.…”

“…For this reason, it is necessary to develop alternative strategies. Chemiluminescence (CL) detection has also been employed in carbamate determination coupled to flow injection (FI) or multicommutation methods 15,16 generally for the determination of a single pesticide, or coupled to LC [17][18][19] for the simultaneous determination of several carbamate pesticides (no more than four pesticides). Post-column luminol reaction, 17 based on the enhancing effect of carbaryl, carbofuran and methiocarb on the oxidation of luminol with permanganate in a basic medium, has been proposed.…”

Royal Society of ChemistryCatalá-Icardo, M.; Meseguer-Lloret, S.; Torres-Cartas, S. (2016 A liquid chromatography method with post-column photoinduced chemiluminescence (PICL) detection is proposed for the simultaneous determination of eight carbamate pesticides, namely aldicarb, butocarboxim, ethiofencarb, methomyl, methiocarb, thiodicarb, thiofanox and thiophanate-methyl. After chromatographic separation, quinine (sensitizer) was incorporated and the flow passed through an UV lamp (67 s of irradiation time) to obtain the photoproducts, which reacted qith acidic Ce(IV) and provided a CL emission. The PICL method showed great selectivity for carbamate pesticides containing sulphur in their chemical structure. A solid-phase extraction process increased sensitivity (LODs ranging from 0.06 to 0.27 ng mL -1) and allowed the carbamate pesticides in surface and ground water samples to be determined, with recoveries in the range 87-110% (except for thiophanate-methyl, whose recoveries were between 60 and 75%). The intraand inter-day precision was evaluated, with RSD ranging from 1.1 to 7.5% and from 2.6 to 12.3%, respectively. A discussion about the PICL mechanism is also included.

“…In fact, CL has been gaining increasing acceptance and has been used to determine OPPs residues in recent years [9][10][11][12][13][14][15]. Nevertheless, practical application of the HPLC-CL technique for the determination of pesticides is still uncommon.…”

A new, fast, selective and sensitive method has been developed for the simultaneous determination of nine organothiophosphorus (OTP) pesticides, namely omethoate, dimethoate, disulfoton-sulfoxide, methidathion, phosmet, malathion, diazinon, pirimiphos-methyl and chlorpyrifos. The pesticides were separated on a Kinetex C18 column by gradient elution with acetonitrile:water. A post-column basic hydrolysis of the pesticides and later a chemiluminescence (CL) reaction with cerium (IV) in acid medium was carried out. Hexadecylpyridinium chloride highly enhanced the CL emission. Under optimized conditions, linearity, precision, limits of detection and quantification, and accuracy were determined. Both selectivity and sensitivity were compared with those obtained with UV detection. In combination with SPE, limits of detection in the range 15-80 ng/L and 5-30 ng/L were obtained when 250 mL and 1000 mL of solution were treated, respectively. When applied to 250 mL of sample the inter-day precision of the method was between 3.5% and 7.3% and the intra-day precision between 2.9% and 6.0%. The method was applied to determine OTP pesticides in spiked water samples from different origins: irrigation, river, sea, ground, spring, mineral and tap waters, being the percentage of recovery of added amounts near 100% form most of the pesticides.

“…Flow injection (FI) methods based on the CL technique are acknowledged in the literature and are used extensively in foods and beverages, ecological, pharmaceutical, and biological analyses. [ 33–38 ] Different FI–CL procedures using Cu(III), Ni (IV) Ag(III), and AuCl 4 − as oxidants have been investigated for medicines, biological fluids, and foodstuff analysis and their analytical characteristics are given in tabulated form. [ 39 ] Recently, hot CL methods have been thoroughly reviewed using quantum dots as sensitizers for analysis of different analytes.…”

Flow injection–chemiluminescence determination of cetirizine dihydrochloride in pharmaceuticals using tris(2,2′‐bipyridyl)ruthenium (II)–Ag(III) complex reaction

A simple and sensitive flow injection–chemiluminescence (FI–CL) method was developed for determination of cetirizine dihydrochloride (CTZH) in pharmaceuticals. The method is primarily based on the enhancement effect of CTZH on the tris(2,2′‐bipyridyl)ruthenium (II)–diperiodatoargentate (III) ([Ru(bpy)3]2+–Ag(III) complex) CL system in an acidic medium. The optimum investigated variables of the CL reaction were: [Ru(bpy)3]2+, 50 × 10−6 mol/L; sulfuric acid, 1.0 × 10−3 mol/L; Ag(III) complex, 100 × 10−6 mol/L; potassium hydroxide, 1.0 × 10−3 mol/L; flow rate, 3.0 ml/min and sample loop volume, 300 μl. The detection and quantification limits were 2.0 × 10−4 and 5.0 × 10−4 mg/L (S/N of 3 and 10) respectively with a linear calibration range of 5.0 × 10−4 to 7.5 mg/L (R2 = 0.9999, n = 11), injection throughput of 110/h and the relative standard deviations of 1.5–3.5% over the range studied. The methodology was successfully applied to determine CTZH in different pharmaceutical samples and validated with a high‐performance liquid chromatography method, and resulted in the recovery of 94.6–108.6%. The probable CL reaction mechanism is described in brief.
