“…The composition of generated waste is extremely variable as a consequence of seasonal circumstances, lifestyle, demographic, geographic, and legislation impacts [3][4][5][6][7][8][9][10][11]. This variability makes defining and measuring the composition of waste more difficult and, at the same time, more essential.…”

Summary. Liquid products produced from two different types of waste pyrolysismunicipal wastes and spent tyre wastes are investigated using gas chromatographymass spectrometry. This method has been applied for detailed identification of composition of the samples. The components were characterized in terms of their Kováts retention indices on a PONA capillary column. The obtained analytical data were successfully used for the characterization of the samples. More than three hundred compounds were detected. The liquid products were complex mixtures, composed mainly of C 4 -C 12 compounds. The examination of the selected m/z values very clearly indicates the existence of the different groups of compounds. With a lot of olefins content (31.9%), followed by aromatics (20.0%), paraffins (17.3%), and naphthenes (7.5%), it is described as the liquid product from pyrolysis of municipal solid wastes. The aromatic compounds in liquid product from pyrolysis of spent tyre wastes have the highest concentration (33.5%), and they are followed by naphthenes (28.6%), olefins (19.2%), and paraffins compounds (7.0%). The present study has shown that the pyrolysis of municipal waste and spent tyres can be used as a means for reduction of environmental pollution and production of liquid product which could be used as a fuel source.

“…A variety of methods requires the accurate and objective assessment of the choice of analytical procedure being faster, reliable, and applicable to various types of waste [11][12][13]. Due to the complexity of the object in terms of current requirements to ensure quality analysis, the task is a challenge for analysts.…”

“…Various methods have been used for extraction of phthalate esters such as solid-phase extraction (Holadova et al, 2007), solid-phase microextraction (Feng et al, 2005;Holadova et al, 2007;Prokupkova et al, 2002) and dispersive liquid-liquid microextraction have gained importance for determination of phthalate esters in water samples (Liang et al, 2008). Liquid-liquid extraction is a simple method for extraction of phthalate esters (Yasuhara et al, 1997). However, the conventional liquid-liquid extraction method needs large quantities of sample and organic solvents (Farahani et al, 2007), the liquid-liquid extraction has been modified so that it can be performed using a small amount of solvent.…”

Phthalate esters are widely used as plasticizer. They can migrate from plastic materials to the environment. Exposure to some of these compounds may increase the risk of getting cancer. Phthalate esters: dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP) were extracted simultaneously using a solid-phase extraction and compared with liquid-liquid extraction and analyzed by a gas chromatograph. The optimum condition method was successfully applied to the analysis of phthalate esters contamination in bottled drinking water samples. The concentration of DMP, DEP and DBP in drinking water samples were below allowable levels, while the DEHP concentration in three samples was found to be greater than the regulatory, maximum admissible concentration.

“…So far, various methods such as liquid-liquid extraction (LLE) [7][8][9], solid-phase extraction (SPE) [10][11][12][13][14], and solid-phase microextraction (SPME) [15][16][17][18][19][20] have been employed as sample pretreatment procedures for the determination of phthalate esters. Among above mentioned sample pretreatment procedures, solid-phase extraction based on the use of different types of adsorbents such as C 18 [7], C 8 [14], PS-DVB [11][12][13][14], and hydroxylated PS-DVB polymers [12] is the most widely used one.…”

Being suspected to have carcinogenic and estrogenic properties, the determination of phthalate esters in various environmental samples is very important for environmental risk assessment. In the present paper, a new solid-phase extraction system for HPLC determination of di-ethyl-phthalate, di-n-propyl-phthalate, di-iso-butyl-phthalate, and di-cyclohexyl-phthalate was developed. The four analytes were quantitatively adsorbed on multi-walled carbon nanotubes packed cartridge, then the analytes were quantitatively desorbed with acetonitrile, finally the analytes in acetonitrile eluate were determined by HPLC. Parameters influencing the extraction efficiency such as volume of sample solutions and eluent volume, were examined. Under the optimized conditions, detection limits of 0.18-0.86 ng ml −1 were achieved for four phthalate esters. The proposed method had been used to determine the four phthalate esters in tap water, river water, and sea water samples. No phthalate esters were found in the river water and sea water samples. For the case of tap water sample, di-ethyl-phthalate, di-n-propyl-phthalate, and di-cyclohexyl-phthalate were not found, only 2.0 ng ml −1 of di-iso-butyl-phthalate was found. The accuracy of the proposed method was tested by recovery measurements on spiked samples, the recoveries of 80.3-104.5% were obtained in most cases.
