REMOVAL OF REACTIVE DYE WITH FLY ASH ADSORPTION

The efectiveness of fly ash in adsorbing Chemactive D Black N from aqueous solutions has been studied as a function adsorbent dosage and initial dye concentration. The Langmuir adsorption ishoterm were found more suitable than Freundlich isotherm. The adsorption capacity Q o was 6.75 mg/g at natural initial pH (pH = 5.40). The removal ratio of dye respectively founded % 100, % 98, % 98, % 82.5, % 66.31 at 5, 10, 25, 50 and 100 mg/L initial dye concentration.

UÇUCU KÜL ADSORPSÝYONU ÝLE REAKTÝF BOYA GÝDERÝMÝ

Uçucu külün sulu çözeltideki reaktif Chemactive D Black N’i adsorplama etkinliði adsorbent dozunun ve baþlangýç boyar madde konsantrasyonunun bir fonksiyonu olarak incelenmiþtir. Adsorpsiyon verilen Freundlich izotermine oranla Langmuir izotermine daha iyi uyum göstermiþtir. Adsorpsiyon kapasitesi ortamýn doðal baþlangýç pH’inde (pH = 5.40) Q o = 6.75 mg/g’dýr. Boyar madde giderim oraný 5, 10, 25, 50 ve 100 mg/L baþlangýç boyar madde konsantrasyonlarýnda sýrasýyla; % 100, % 98, % 98, % 82.5, % 66.31 olmuþtur.
