ENDÜSTRİYEL ARITMA ÇAMURLARINDAKİ POLİAROMATİK HİDROKARBONLARIN (PAH'LARIN) SICAKLIK VE UV IŞINLARI ETKİSİYLE HAVAYA GEÇİŞİNİN İNCELENMESİ

Bu çalışmada, otomotiv endüstrisi arıtma çamurlarındaki poliaromatik hidrokarbonların (PAH'ların) sıcaklık ve UV uygulamaları sonrasında hava ortamına geçişleri incelenmiştir. Deneysel çalışmalar için özel olarak tasarlanmış düzenekte yüksek enerjili UV-C lambaları kullanılmıştır. Poliüretan köpük (PUF) içeren kolonlar düzenek giriş ve çıkışına yerleştirilerek iç ortam havası 24 saat boyunca vakumlanmıştır. Düzenek girişindeki PUF kolonu dışarıdan düzeneğe giren PAH'ları tutarken düzenek çıkışındaki kolon ise buharlaşan PAH'ların örneklenmesi için kullanılmıştır. Deneysel çalışmalar 3 tekrarlı yapılmıştır. Tüm sıcaklık değerlerinde, çamurdan havaya geçen PAH'ların ortalama %82'sinin 3 halkalılardan oluştuğu tespit edilmiştir. Sıcaklık uygulamaları sonunda çamurdaki PAH'ların maksimum %57'si havaya geçmiştir (37oC'de-UV yokken). UV uygulamalarında ise bu değer %71'e ulaşmıştır (37 oC'deUV varken). Çamurdan havaya geçen PAH miktarı sıcaklığın 8oC'den 37oC'ye yükselmesiyle artış göstermiştir.

Migration of Polycyclic Aromatic Hydrocarbons (PAHs) from Industrial Treatment Sludge to Air with the Effect of Temperature and UV Light

In this study, the migration of polycyclic aromatic hydrocarbons (PAHs) from the automotive industry treatment sludge to air with the effect of temperature and UV light were investigated. In the apparatus specifically designed for experimental studies, UV-C lamps with high energy were used as a light source. By placing the columns containing polyurethane foam (PUF) on the inlet and outlet of the apparatus, the inside air was vacuumed for 24 hours. While the inlet PUF column kept PAHs entering the apparatus, the outlet column was used to collection of the evaporated PAHs. All the experiments were repeated three times. Average 82% of migrated PAHs consisted of 3-ring compounds at all temperatures. While 57% of PAHs in the sludge migrated to air during temperature application (37 oC-without UV), this value increased to 71% during UV application (37oC-with UV). The amounts of migrated PAHs were increased with increasing of temperature from 8 oC to 37 oC.
