REAKTİF JAKOFİX YELLOW İÇEREN BOYA ÇÖZELTİLERİNİN ELEKTROKOAGÜLASYON PROSESİ İLE RENK GİDERİMİ: BAZI ELEKTROKİMYASAL DEĞİŞKENLERİN İNCELENMESİ

Öz

   Atıksudan boya giderimi, tekstil endüstrisinin su kirliliği ile ilgili başlıca çevresel problemlerinden biridir. Günümüzde çevre üzerindeki olumsuz etkisini azaltma açısından renk gideriminin optimizasyonu önemli bir husustur. Bu çalışma, üç farklı tür elektrot çifti kullanarak kesikli-karıştırmalı bir sistemde Jakofix Yellow boyası içeren reaktif boya çözeltilerinin renk giderimi üzerine yapıldı. Arıtımı optimize etmek için akım yoğunluğu, işlem zamanı, elektrot tipi ve başlangıç pH değeri gibi farklı işletme şartları boya çözeltilerinde test edildi. Yapılan denemelerde elde edilen optimum işletme koşulları: kesikli-karıştırmalı sistem için akım yoğunluğu 196 A m^-2, başlangıç pH’sı doğal pH değeri olan 5.5 ve Fe-elektrotlardır. Elde edilen bu sonuçlar, Jakofix Yellow tekstil boyası içeren atıksuların renk giderimi için EC prosesinin oldukça basit ve etkili bir arıtım metodu olduğunu ve bu tekniğin etkinliğini arttırmak için kil minerallerinin kullanılabileceğini net bir şekilde göstermektedir.

DECOLORIZATION OF DYE SOLUTION CONTAINING REACTIVE JAKOFIX YELLOW BY ELECTROCOAGULATION PROCESS: INVESTIGATION OF SOME ELECTROCHEMICAL VARIABLES

Öz

   Dye removal from effluent is one of the major environmental problems in textile industry concerning water pollution. Nowadays the optimization of the decolorization processes is a considerable topic in that minimizing the negative impact on the environment,. The present work deals with the decolorization of reactive dye solutions containing Jakofix Yellow dye in a batch-stirred electrocoagulation (EC) cell using three different types of electrode pair. Different operating conditions, such as current density, operating time, electrode type and initial pH value were tested with the dye solutions in order to optimise the treatment.  Optimum operation conditions achieved in the tests were: current density of 196 A m-2, initial pH of 5.5 which its natural value and Fe electrodes for the batch-stirred setting. Results clearly show that EC process is quite simple and effective treatment method for decolorization of wastewaters containing textile dye jakofix yellow and clay minerals can be used in order to increase the efficiency of this technique.
