“…A small piece of particulate laden PTFE filter measuring an area of 3.14 cm 2 was taken for extraction in a dark bottle by adding one mL of dichloromethane:methanol (60 : 40) mixture. Then the filter and solvent mixture was allowed to incubate for half an hour and then ultrasonically extracted for another half an hour [ 20 ]. The process was repeated 2-3 times, and final volume was made up to 2 mL.…”

Coimbatore is one of the fast growing industrial cities of Southern India with an urban population of 1.9 million. This study attempts to evaluate the trends of airborne fine particulates (PM 2.5) and polyaromatic hydrocarbons (PAH) on them. The PM 2.5 mass was collected in polytetra fluoroethylene filters using fine particulate sampler at monthly intervals during March 2009 to February 2010. PAHs were extracted from PM 2.5 and estimated by high-performance liquid chromatography. It is alarming to note that PM 2.5 values ranged between 27.85 and 165.75 μg/m3 and exceeded the air quality standards in many sampling events. The sum of 9 PAHs bound to PM 2.5 in a single sampling event ranged from 4.1 to 1632.3 ng/m3. PAH diagnostic ratios and principal component analysis results revealed vehicular emissions and diesel-powered generators as predominant sources of PAH in Coimbatore.

“…Several analytical techniques that have been used earlier were carefully considered for extraction efficiency, accuracy, detection limits, and cost, and finally, an appropriate method was evaluated (Sikalos et al 2002;Vasconcellos et al 2003;Bourottea et al 2005;Ryno et al 2006;Rajput and Lakhani 2009). In the present investigation, PAH extraction and analysis were carried out as per modified Colombini et al (1998) method. PTFE membrane filter carrying PM 2.5 was ultrasonically extracted by dichloromethane:methanol (60:40) mixture in a dark bottle for 2-3 times.…”

“…[1][2][3][4][5][6][7] Researches have been focused on the development of stationary phases capable of making good use of the p-p interaction between p electrons of a sample and a ligand, immobilized on a support, having p electrons. [8][9][10][11][12] There are commercially available columns of which separation mechanism is mainly based on the p-p interaction, such as PYE ® column, wherein 2-(1-pyrenyl)ethyl group is immobilized on silica gels.…”

were purchased from Aldrich, U.S.A. Phthalocyanine (H 2 -PC) was obtained from Tokyo Kasei, Japan. As a supports, Develosil NH 2 -5 ® (hereinafter, referred to as "Dev", Nomura Kagaku, Japan) which is a spherical aminopropyl silica gels (particle size, 5 mm; specific surface area, 350 m 2 /g; average pore size, 120 Å) was used. As an eluent, n-hexane for HPLC (Nacalai Tesque, Japan) was mainly used, and as a solvent for packing M-PCS D , slurry solvent A Conc. (Chemco Scientific, Japan) was used. The commercially available PYE ® column and NPE ® (nitro-phenylethyl silica gels) column (Nacalai Tesque, Japan) were used for comparison to elucidate the underlying separation mechanism of the M-PCS D column. M-PCS D ColumnsMetal-phthalocyanine tetrasulfonyl chloride (MPCSCl: MϭH 2 , Ni 2ϩ and Cu 2ϩ , see Fig. 1) was synthesized from H 2 -PC, Cu-PC and Ni-PC as described by Nadler et al.17) The resultant Ni-PCSCl (5.6 mg), Cu-PCSCl (5.6 mg) or H 2 -PCSCl (5.3 mg) was each dissolved in dioxane (150 ml), following the addition of Dev (1.5 g), and was refluxed for 2 h. After standing to cool, M-PCS D was separated by filtration, and washed with methanol (100 ml), dried thoroughly in vacuo over diphosphorous pentoxide. The M-PCS D column was then prepared by packing the obtained M-PCS D into a stainless-steel column (f4.6ϫ150 mm) for HPLC by a conventional slurry packing method. Throughout the process, the filtrate and the like were clear and colorless, and the absorption spectra thereof were free from characteristic absorption band(s) of M-PCSCls or M-PCSs. From these evidences, it was concluded that M-PCS was completely immobilized on silica gels. The amount of M-PCS immobilized was also estimated from the absorption spectrum of the initial M-PCS solution in dioxane.
