The removal of Astrazon Black MBL with an innovative adsorbent: Optimization of operating parameters with Taguchi method

Various dyes are used in the textile industry. Azo dyes, stable and toxic, constitute the majority of these dyes. In this study, the removal of Astrazon Black MBL belonging to azo group with an innovative adsorbent was investigated. The efficiency of adsorbent was evaluated in terms of color removal, oxidation and reduction potential (ORP), FTIR (Fourier Transform Infrared Spectrometer), pH and ion count, and the results were optimized with Taguchi method. As a result of the study, color removal efficiency in the range of 98.4% - 99.6% was obtained with the innovative adsorbent used. The pH and ORP of the liquid products after adsorption was measured in the range of 6.10-6.89 and in the range of 18.1-64.2 mV, respectively. From FTIR analysis results, Astrazon Black MBL dye was observed to be very stable. As a result, it was observed that waste can be evaluated successfully with adsorbent used in the study. In addition, since the adsorbent used does not have a cost, it provides the applicability of the method in terms of cost because the operating cost is low.

Astrazon Black MBL boyasýnýn yenilikçi bir adsorbent ile giderimi: Taguchi metodu ile iþletme parametrelerinin optimizasyonu

Tekstil sanayisinde çeþitli boyalar kullanýlmaktadýr. Bu boyalarýn büyük kýsmýný da kararlý ve toksik olan azo boyalarý oluþturmaktadýr. Bu çalýþmada azo boya gruplarýndan Astrazon Black MBL boyasýnýn yenilikçi bir adsorbent ile giderimi araþtýrýlmýþtýr. Adsorbentin verimi renk giderimi, oksidasyon ve redüksiyon potansiyeli (ORP), FTIR (Fourier Transform Infrared Spectrometer), pH ve iyon sayýsý açýsýndan ele alýnmýþtýr ve elde edilen sonuçlar Taguchi metodu ile optimize edilmiþtir. Çalýþma sonucunda kullanýlan yenilikçi adsorbent ile %98.4-%99.6 aralýðýnda renk giderim verimi elde edilmiþtir. Adsorpsiyon sonrasý sývý ürünlerin pH’ý 6.10-6.89 aralýðýnda ve ORP 18.1 ve 64.2 mV aralýðýnda ölçülmüþtür. FTIR analizi sonuçlarýndan Astrazon Black MBL boyasýnýn çok kararlý olduðu gözlenmiþtir. Sonuç olarak çalýþmada kullanýlan adsorbent ile atýðýn baþarýlý bir þekilde deðerlendirilebileceði gözlenmiþtir. Ayrýca kullanýlan adsorbent bir maliyete sahip olmadýðý için iþletme maliyetinin az olmasýndan dolayý maliyet açýsýndan da yöntemin uygulanabilirliðini saðlamaktadýr.
