DYE REMOVAL FROM TEXTILE WASTEWATER BY ADSORPTION METHOD

Öz

The widespread use of indigo dyes, especially in denim production in the textile industry, makes their removal difficult with biological treatment methods. The fact that their chemical structures are difficult to biodegrade causes significant negative effects on the environment. For this reason, more economical, efficient and sustainable advanced treatment methods are needed to remove indigo dyes. The adsorption method is a prominent solution with its low cost, efficiency and environmentally friendly structure. In this study, the potential of walnut shell to be used as an adsorbent in removing indigo dyes was investigated and its performance at different concentrations was analyzed in detail. The results showed that walnut shell provided at least 71% dye removal at concentrations between 0.1 gr/L and 5 gr/L. In addition, the efficiencies of two different adsorbents, fly ash and walnut shells, were compared and it was determined that walnut shell provided 90% color removal and fly ash provided 86% color removal. Walnut shell proved to be a promising biosorbent in the removal of indigo dyes by providing high removal efficiency even at low concentrations. These findings show that walnut shells are a more advantageous option compared to fly ash, both economically and environmentally. The use of natural materials, especially biosorbents such as walnut shells, in wastewater treatment supports an environmentally friendly approach by providing sustainable and economical solutions.

TEKSTİL ATIKSULARINDAKİ BOYARMADDENİN ADSORPSİYON YÖNTEMİ İLE GİDERİMİ

Öz

Tekstil endüstrisinde, özellikle kot üretiminde kullanılan indigo boyalarının giderimi, biyolojik arıtım yöntemleriyle zor olmaktadır. Bu boyalar, kimyasal yapıları nedeniyle biyolojik olarak zor parçalanır ve bu durum çevresel sorunlar yaratır. Bu nedenle, indigo boyalarının etkili bir şekilde giderilmesi için daha ekonomik ve verimli ileri arıtım yöntemlerine ihtiyaç duyulmaktadır. Adsorpsiyon, düşük maliyetli, etkili ve çevre dostu bir yöntem olarak öne çıkmaktadır. Çalışmada, ceviz kabuğunun farklı konsantrasyonlardaki performansı detaylı olarak incelenmiştir. Ceviz kabuğunun 0.1 gr/L ile 5 gr/L arası konsantrasyonlarında en az %71 oranında renk giderimi sağladığı tespit edilmiştir. Uçucu kül ve ceviz kabuğu olmak üzere iki farklı adsorbent karşılaştırılmıştır. Yapılan analizlerde, ceviz kabuğunun %90, uçucu külün ise %86 oranında renk giderimi sağladığı belirlenmiştir. Bu sonuçlar, ceviz kabuğunun düşük konsantrasyonlarda bile etkin bir adsorbent olduğunu ortaya koymaktadır. Ceviz kabuğu, ekonomik ve çevresel açıdan uçucu küle kıyasla daha avantajlıdır. Düşük konsantrasyonlarda dahi yüksek giderim verimi sunması, ceviz kabuğunu indigo boyalarının gideriminde umut verici bir biyosorbent haline getirmektedir. Doğal malzemelerin, özellikle ceviz kabuğu gibi biyosorbentlerin atık su arıtımında kullanımı, sürdürülebilir ve ekonomik çözümler sunmaktadır.
