Abstract

In this study, the removal of alizarin red dye by hydroxyapatite was investigated with the adsorption process. The effects of shaking speed, pH, hydroxyapatite dose and the initial dye concentration were studied on the removal of dye. The adsorption of alizarin red dye using hydroxyapatite was found to be more appropriate to the pseudo second order kinetic model and the Freundlich isotherm model. The maximum adsorption capacity was obtained as 144.9 mg/g at pH 7 and 1 g/L hydroxyapatite after 150 minutes adsorption. As a result, it is thought that hydroxyapatite can be used as an alternative adsorbent to remove the anionic dyes such as alizarin red dye.

Özet

Bu çalışmada, hidroksiapatit ile alizarin kırmızı boyasının adsorpsiyon prosesiyle giderimi araştırılmıştır. Çalışmada çalkalama hızının, çözelti pH değerinin, hidroksiapatit miktarının ve başlangıç boya konsantrasyonun giderim verimi üzerine etkisi ortaya konmuştur. Alizarin kırmızı boyasının hidroksiapatit ile adsorpsiyonu yalancı ikinci dereceden kinetik modele ve Freundlich izoterm modeline daha uygun olduğu görülmüştür. Maksimum adsorpsiyon kapasitesi pH 7’de, 1 g/L hidroksiapatit ile 150 dakika adsorpsiyon sonucunda 144,9 mg/g olarak elde edilmiştir. Sonuç olarak, hidroksiapatitin alizarin kırmızı boyası gibi anyonik boyaların gideriminde alternatif bir adsorbent olarak kullanılabileceği düşünülmektedir.
