Abstract (2. Language): 
Thallium has been identified to be an environmentally important element because of its toxic effects. Owing to the high toxicity of thallium, even slightly contamination has been found to cause severe damages, such as loss of hair, nervous disease, impaired vision and growth retardation. This compound is used in optical systems, low temperature thermometers, dye pigments, photoelectric cells, and chemical synthesis. Determination of trace amounts of thallium is of great importance because of its toxic nature and also its increasing industrial applications. The main sources of thallium pollution at present are cement production and fossil fuel combustion. Thallium can be found in two different oxidation states, Tl (I) and Tl (III). Although Tl (I) is more stable in aqueous solutions, Tl (III) forms complexes of greater stability. Therefore, the determination of chemical species in the environmental samples is important and it has considerably increased interest in the last few years.

Abstract (Original Language): 
Talyum zehirli etkilerinden dolayı çevresel olarak önemli bir element olarak tanımlanmaktadır. Talyumun yüksek zehirliliği nedeniyle çok düşük düzeyde bulaşması bile saç kaybı, sinir hastalıkları, görme zayıflığı, büyüme gecikmesi gibi ciddi hasarlara neden olabilmektedir. Bu bileşik optik sistemlerde, düşük sıcaklık termometrelerinde, boya pigmentlerinde, fotoelektrik hücrelerinde ve kimyasal sentezlerde kullanılır. Talyumun eser miktarını belirleme zehirli yapısı ve artan endüstriyel uygulamalarından dolayı büyük bir önem taşır. Günümüzde talyum kirliliğinin ana kaynakları çimento üretimi ve fosil yakıtların yanmasıdır. Talyum, Tl (I) ve Tl (III) olmak üzere iki farklı yükseltgenme basamağında bulunabilir. Tl (I) sulu çözeltilerde daha kararlı olmasına rağmen, Tl (III) daha kararlı kompleksler oluşturur. Bundan dolayı çevresel örneklerde kimyasal türlerin belirlenmesinin önemi son birkaç yılda hızla artmıştır.
