“…In our previous attempts, we modified SPE membrane disks with suitable compounds for selective determination of chromium [18][19]36 and lead 21 . Meanwhile, other investigators have successfully utilized these sorbents for quantitative extraction and monitoring trace amounts of lead [22][23][24] , copper [25][26] , silver [28][29] , mercury [30][31] , cadmium 32 , palladium 33 , Ce 34 and UO 2 35 .…”

A novel, simple, sensitive and effective method has been developed for preconcentration of Cr (III) on functionalized Graphene oxide with covalently linked porphyrin (GO-H 2 NP) solid-phase extraction adsorbent. The stability of a chemical (GO-H 2 NP), especially in concentrated hydrochloric acid, was then used as a recycling and pre-concentration reagent. The method is based on selective chelation of Cr(III) on surfactant coated C 18 , modified with functionalized GO with covalently linked porphyrin (GO-H 2 NP). The retained ions were then eluted with 4 ml of 3 M nitric acid and determined by flame atomic absorption spectrometry (FAAS) at 283.3nm for Cr. The influence of flow rates of sample and eluent solutions, pH, breakthrough volume, effect of foreign ions on chelation and recovery were investigated. 1.5 g of surfactant coated C 18 adsorbs 40 mg of the functionalized Graphene oxide with covalently linked porphyrin (GO-H 2 NP) base which in turn can retain 20.0± 0.9 mg of each of the two ions. The limit of detection (3s) for Cr (III) was found to be 6.00 ng l -1 . The enrichment factor for both ions is 100. The mentioned method was successfully applied on the determination of Cr in different water samples. The ions were also speciated by means of a three columns system.

“…GO [36] (15 mg) was stirred in 20 mL of oxalyl chloride at 80 °C for 24 h to activate the carboxylic units by forming the corresponding acyl chlorides. Then, the reaction mixture was evaporated to remove the excess oxalyl chloride and the brownish remaining solid (GO-COCl) was washed with anhydrous tetrahydrofuran (THF).…”

“…This 103.8 mg wholerock powdered sample was dissolved and analyzed by quadrupole ICPMS (PQ Excell, ThermoElectron Corporation, Waltham, MA, USA) using methodology and instrumentation described in Wolf et al (2005). For this work, calibration involved the standard addition method with internal standardization.…”

“…The analytical figures of merit of ICPMS rival that of RNAA and, because its high sample throughput capabilities facilitate the measurement of multiple blanks and application of time-dependent external drift corrections, ICPMS offers the possibility that it can supplant RNAA as the technique of choice for quantifying our suite of highly labile trace elements (cf. Wolf et al 2005), even in lunar samples.…”

(DaG 476) and incorporate these into a comparative study of basaltic meteorites from the Moon, Mars, and V-type asteroids. Multivariate cluster analysis of data for these elements in 14 lunar, 13 Martian, and 34 howardite, eucrite, and diogenite (HED) meteorites demonstrate that materials from these three parents are distinguishable using these markers of late, low-temperature episodes. This distinguishability is essentially as complete as that based on markers of high-temperature igneous processes. Concentrations of these elements in 14 lunar meteorites are essentially lognormally distributed and generally more homogeneous than in Martian and HED meteorites. Mean siderophile and labile element concentrations in the 14 lunar meteorites indicate the presence of a CI-equivalent micrometeorite admixture of 2.6%. When only feldspathic samples are considered, our data show a slightly higher value of 3.4% consistent with an increasing micrometeorite content in regolith samples of higher maturity. Concentrations of labile elements in the 8 feldspathic samples hint at the presence of a fractionated highly labile element component, possibly volcanic in origin, at a level comparable to the micrometeorite component. Apparently, the process(es) that contributed to establishing lunar meteorite siderophile and labile trace element contents occurred in a system open to highly labile element transport.

“…However, these methods are laborious and are apt to carry a risk of contamination. A variety of methods have been proposed for the determination of thallium such as inductively coupled plasma (Miyazaki et al, 1992), inductively coupled plasma-mass spectroscopy (Takeda et al, 2001;Wolf et al, 2005), atomic absorption spectroscopy (Carpenter, 1981;Silva et al, 2004), X-ray fluorescence (Mihajlovic and Stafilov, 1998), electroanalytical methods (Ciszewski et al, 1997;Shams and Yekehtaz, 2002; ABSTRACT: Methylene blue has been proposed as a new analytical reagent for the catalytic spectrophotometric determination of thallium (I). It reacts with ascorbic acid in acidic medium to form a colorless product.…”
