Elektrokoagülasyon
koloitlerin atıksulardan giderilmesinde kullanılan önemli arıtma yöntemlerinden
biridir. Boyarmaddeler atıksulardaki önemli koloit kaynaklarının başında
gelirler. Tekstil endüstrisinde oldukça fazla kullanılan boyarmaddeler,
endüstrinin kullandığı su miktarının fazlalığı da göz önüne alındığında alıcı
su ortamları için önemli koloidal kirleticiler haline gelirler. Bu çalışmada
farklı molekül ağırlığındaki iki ayrı tekstil boyar maddesi kullanılarak
kirletici koloitlerin molekül ağırlığının elektrokoagülasyonda giderme verimine
ne şekilde etki ettiği incelendi. Bu amaçla alüminyum elektrotların
kullanıldığı reaktöründe renk giderme çalışmaları yapıldı. Çalışma farklı pH
değerlerinde yapılarak farklı flok yapılarının (büyüklüklerinin) etkileri de
incelendi. pH artışından daha büyük molekül
ağırlığına sahip olan boyarmadde daha çok etkilendiği tespit edildi. Boyarmadde
gidermede daha büyük molekül ağırlığına sahip olan Reactive Black 39 (1021.16
g/mol) pH değişiminden % 100 ‘den 74.83 ‘e düşüşle, yaklaşık % 25 oranında
etkilenirken, daha küçük molekül ağırlığına sahip olan Remazol Red 3B (674.10
g/mol) % 96.54 ‘den 83.01 ‘e düşüşle yaklaşık % 13 oranında etkilenmektedir.

Molecular Weight and pH Effect on Removal of Dyestuffs from Water by Electrocoagulation Method

Öz

Electrocoagulation
is one of the important treatment methods used to remove colloids from
wastewater. Dyestuffs are the leading source of colloids in wastewaters.
Dyestuffs, which are used extensively in the textile industry, become important
colloidal pollutants for the receiving water environments, given the increased
amount of water used by the industry. In this study, the effect of molecular
weight of pollutant colloids on the removal efficiency of electrocoagulation
was investigated by using two different textile dye materials with different
molecular weights. For this purpose, color removal studies were carried out in
the reactor where aluminium electrodes were used. The study was carried out at
different pH values ​​and the effects of different flock structures (size) were
also studied. It was found that the pH a was more affected than the dye having
a larger molecular weight. The Reactive Black 39 (1021.16 g / mol), which has a
higher molecular weight in the dyestuffs, has Remazol Red 3B (674.10 g / mol),
which has a smaller molecular weight, while being affected by a change of pH
from 75% to 74.83% It is affected by 13%, down from
96.54 to 83.01.
