“…Only C. sativum L. is cultivated widely in the tropics. India has the prime position in the cultivation and production of Coriander (Sharma and Sharma 2004). The seeds contain an essential oil “linalool” a monoterpenoid and the leaves contain substantial amounts of caffeic acid, ferulic acid, gallic acid, and chlorogenic acid (Bajpai and others 2005).…”

“…For this reason, the limits of detection are absolutely inadequate [39], considering that the concentrations of such metals in the matrices of interest are decidedly very low. This is so much so that, to better the limits of detection, differential pulse voltammetry was employed always coupled to complementary chemical procedures, as preconcentration by solvent extraction [40,41], modified electrodes [42 -46], or to mathematical procedures of treatment and optimization of the voltammetric signal [40,47,48]. So, to obtain suitable limits of detection for the determination of PGMs in the real matrices of interest, it was immediately evident the necessity to set up procedures addressed to concentrate such metals onto the working electrode.…”

“…Recently, voltammetric procedures for analytical determination of ultratrace osmium [48], sometimes using modified electrodes [112,113] have been suggested. Such procedures have found very interesting applications in seawater and human urine [112] and industrial waste water [113] matrices.…”
The compelling use of autocatalytic converters, containing platinum group metals (PGMs), has been the cause, in the environmental and biological matrices, of an increasing concentration of such metals. For this reason, in the last decade, the literature has reported several papers regarding analytical procedures for the determination of Pt(II), Pd(II) and Rh(III) in real samples, generally employing spectroscopic methods. The present review intends to highlight the contribution of the voltammetric techniques for the determination of these metals, including also those less investigated, i.e. Iridium, Osmium and Ruthenium.
“…The crop grows in tropics and requires a cool but comparatively dry frostfree climate, particularly at flowering and seed formation stages (Sharma and Sharma, 2004). It is cultivated throughout the world both for seed and leaf purpose.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
