“…Unlike these techniques, Ultraviolet-visible (UV-vis) spectroscopy is a simple instrument, cheap, easy operated, rapid response time, available in many laboratories. But, the CPE was efficiently coupled with spectrophotometry and spectrofluorometry, and successfully used in order to increase its low detection limit as well as the selectivity of the technique (Gurkan and altunay 2013;Jamshid et al 2006;Madrakian and Ghazizadeh 2009). …”

In the present study, an inexpensive, selective, and micellar sensitive spectrophotometric method for Sn(IV) was developed at 537 nm. The method is based on the formation of ternary complex of Sn(IV) with tartaric acid and Celestine blue in the presence of sodium dodecyl sulfate (SDS) and polyethylene glycol tert-octylphenyl ether (Triton X-114) at pH 3.5. The analytical variables affecting cloud point extraction (CPE) efficiency were optimized in detail. Under the optimized conditions, the calibration graph was linear in the range of 4-350 μg L −1 with changing dye concentration for Sn(IV) ions. The limits of detection and quantification of the method were found to be 1.3 and 4.3 μg L −1 for Sn(IV), respectively. Relative standard deviation (RSDs) for five replicate determinations at 20 and 100 μg L −1 concentration levels were 4.4 and 1.5 %, respectively. Recovery values of spiked samples were obtained in range of 97.7-103.3 %. Matrix effect on the extraction efficiency were also investigated. The method was successfully applied to the determination of Sn(II), Sn(IV) and total Sn in some selected beverages before and after pretreatment with H 2 O 2 in acidic media, prior to analysis. Validity of the method was controlled through the analysis of two certified reference materials. It has been observed that the results are highly compatible with the certified values.

“…In contrast spectrophotometric methods are preferred due to their simplicity and speed in routine analysis. The reported studies have shown that a large number of reagents such as methyl orange [11], benzopyran derivatives [1,12,13], 2-(5-nitro-2-pyrilazo)-5-[N-n-propyl-N-(3-sulfopropyl)amino-phenoyl] [14], pyrocatechol violet [15][16][17][18], phenylfluorone [19,20], dibromohydroxyphenylfluorone [21], arsenazo-M [22], isoamyl xanthate [23], diacetylmonoxime-p-hydroxybenzoyl-hydrazine [24], bromopyrogallol red [25], potassium ethylxanthate [26], ferron [27], and 5,7-dichloro-8-quinolinol [28] have been used for the spectrophotometric determination of tin(II,IV) content. Among these many reagents [18,21,23,[26][27][28] are nonselective as they suffer from the interference, have low sensitivity [11,12,23,24,[26][27][28], and some of them are time consuming, as they require time for full color development [14,18,20].…”

Some of the sensitive reagents [16,17,21,22,25] are reported, but these require the use of the surfactants, plasticizer, and critical pH adjustment. Thus in the view of the above facts it reveals that there is still a lot of scope for working out new methods and effecting amendments in the existing ones especially because of their lower sensitivity and selectivity.…”

An extractive spectrophotometric method for the determination of the trace amounts of tin has been carried out by employing 6-chloro-3-hydroxy-2-(2 -thienyl)-4-oxo-4H-1-benzopyran (in acetone) (CHTB) for the complexation of the metal ion in HCl medium. The colored species thus produced is quantitatively extracted into dichloromethane and shows the maximum absorbance at 432-437 nm. The method obeys Beer's law in the range 0.0-1.3 g mL −1 of tin with molar absorptivity and Sandell's sensitivity of 5.81×104 L mol −1 cm −1 and 0.0020 g Sn cm −2 , respectively, at 435 nm. The method is highly selective and free from the interference of a large number of elements including platinum metals. The ratio of metal to ligand in the extracted species is 1 : 2. Utilizing this method, the analysis of various synthetic and technical samples including gun metal and tin can have been carried out satisfactorily.

An environmentally friendly analytical procedure for nickel determination by atomic and molecular spectrometry after cloud point extraction in different samples

Cloud point extraction (CPE) was employed for separation and preconcentration prior to the determination of nickel by graphite furnace atomic absorption spectrometry (GFAAS), flame atomic absorption spectrometry (FAAS) or UV-Vis spectrophotometry. Di-2-pyridyl ketone salicyloylhydrazone (DPKSH) was used for the first time as a complexing agent in CPE. The nickel complex was extracted from the aqueous phase using the Triton X-114 surfactant. Under optimized conditions, limits of detection obtained with GFAAS, FAAS and UV-Vis spectrophotometry were 0.14, 0.76 and 1.5 mg L À1 , respectively. The extraction was quantitative and the enrichment factor was estimated to be 27. The method was applied to natural waters, hemodialysis concentrates, urine and honey samples. Accuracy was evaluated by analysis of the NIST 1643e Water standard reference material.
