dc.description.abstract | A method was developed and validated for the analysis of benzene, toluene, ethylbenzene, xylene (BTEX), and styrene in sea water samples using gas chromatography-mass spectrometry (GC-MS) with static headspace extraction. To carefully characterize the performance of this method, several factors affecting the parameters were studied in detail, such as the heating procedure, loop filling time, equilibrium temperature, the sample dilution ratio, equilibrium, and injection times. The optimized conditions are as follows: 1)the heating procedure, 50 degrees C for 4 min, then increased to 170 degrees C at 15 degrees C min-1, 2) equilibrium temperature, 60 degrees C, 3) equilibrium time, 5 min, and 4) injection time 0.5 min. Under the optimized conditions, the linear equations were obtained in the concentration range of 10 - 50 /kg L-1 with good correlation coefficient values. The limits of detection were 1.8 - 3.3 mu g L-1. The recoveries at the spiked level of 20 mu g L-1 BTEX and styrene ranged from 97% - 103% with the relative standard deviations were (RSD, n=3) 1.0% - 7.6%. The method was used for seawater samples from the Marmara Mudanya region. | en_US |
dc.description.abstract | Deniz suyundaki benzen, toluen, etilbenzen, ksilen ve stiren bileşenlerinin tayininde gaz kromatografisi metodu kullanılmaktadır. Bunun için örnekler statik buhar faz ekstraksiyon yöntemiyle gaz faza alınıp gaz kromatografisi kütle spektrometresine enjekte edilmektedir. Analiz sonuçlarına etki edebilecek parametrelerden en önemlileri araştırılarak, gerçek deniz suyu örneğinin film kompozisyonu en önemli faktör olarak saptanmıştır. Cihazda kullanılan fırın programı; 50°C, 4 dk boyunca, 15°C dk-1 artış hızı ile 170°C’ ye ısınma şeklindedir. Enjektör sıcaklığı 280°C’ dir. Optimize edilen şartlarda, kullanılan analitik bölge aralığında (10-50 μg L-1), yüksek korelasyon katsayıları elde edilmiştir. Gözlenebilme sınırları 1,8-3,3 μg L-1 aralığındadır. Geri kazanım verimleri, 20 μg L-1 katılımlar için %97’nin üzerinden bulunurken, bağıl standart sapmalar ise %1 ile %8 arasında değişmektedir. Geliştirilen yöntem Marmara Denizi Mudanya kıyılarından alınan deniz suyu örneklerine uygulanmıştır. | tr_TR |
