Abstract

Decolourisation of wastewater, particularly from textile industries, is one of the major environmental concerns these days. Current methods for removing dyes from wastewater are costly and cannot effectively be used to treat wide range of such wastewater. This work describes the use of commercial available granular activated carbon (GAC) as an efficient adsorbent material for dyes removal. Aqueous solutions of various basic dye Methylene Blue (MB) and azo-dye Tartrazine with concentrations 5-20 mg l^–1 and 10-100 mg l^–1, respectively, were shaken with certain amount of GAC to determine the adsorption capacity and removal efficiencies. The effects of adsorbent dose, initial pH, initial dye concentration, agitation speed and contact time on dyes removal efficiencies have been studied. Maximum dye concentration was removed from the solution within 60-90 min after the beginning of every experiment. Adsorption parameters were found to fit well into Langmuir and Freundlich adsorption isotherms models with correlation coefficient (R² > 0.99) in the concentration range of MB and TZ studied.

YAPAY ÇÖZELTİLERDEN BİR BAZİK VE BİR AZO BOYAR MADDESİNİN AKTİF KARBON KULLANILARAK ADSORPSİYONUYLA GİDERİLMESİNİ ETKİLEYEN FAKTÖRLER

Abstract

Özellikle tekstil endüstrisinden gelen atık suların renginin giderilmesi günümüzde büyük çevresel kaygılardan birini oluşturmaktadır. Atık sudan boyar maddelerin giderilmesini içeren şu andaki yöntemler pahalıdır ve böyle atık suların geniş ölçekte ele alınmasında etkili olarak kullanılamaz. Bu çalışma, boyar maddelerin giderilmesinde etkili bir adsorban malzeme olarak ticari olarak mevcut granül aktif karbon (GAK) kullanımını tarif etmektedir. Bazik bir boyar madde olan Metilen Mavisi (MB) ve azo boyası olan Tartrazin'in sırası ile 5-20 mg.L-1 ve 10-100 mg.L-1 olarak değişen konsantrasyonlarında sulu çözeltileri belirli miktarda GAK ile çalkalanmış ve adsorpsiyon kapasiteleri ile giderme etkinlikleri belirlenmiştir. Adsorban dozu, ilk pH, ilk boya konsantrasyonu, çalkalama hızı ve temas süresinin boyaların giderme etkinlikleri üzerine etkileri incelenmiştir. Maksimum boya derişimi, her deneyin başından itiberin 60-90 dakika içinde çözeltiden giderilmiştir. Adsorpsiyon parametreleri Langmuir ve Freundlich adsorpsiyon izoterm modellerine, çalışılan MB ve TZ derişim aralıkları içinde iyi bir şekilde uymaktadır (R2 > 0,99).
