Abstract:In the present study the adsorption of Reactive Blue 19 dye on the hydroxyapatite (HAp) nanopowders was investigated. The batch adsorption experiments were performed by monitoring the adsorbent dosage, contact time, dye solution concentration, pH and temperature. At pH 3 and 20ºC, high dye removal rates of about 95.58% and 86.95% for the uncalcined and calcined nanohydroxyapatites, respectively, were obtained. The kinetic studies indicated the dye adsorption onto nanohydroxyapatite samples to follow a pseudo-second order model. The Langmuir isotherm was found to be the best to represent the equilibrium with experimental data. The maximum adsorption capacity of uncalcined and calcined nanohydroxyapatite samples has been found to be 90.09 mg/g and 74.97 mg/g, respectively.

“…Numerous physical and chemical processes have been investigated for dye removal from wastewater such as adsorption 7,8 , coagulationflocculation 9 , biosorption 10 , ultrafiltration 11 and photocatalytic degradation 12,13 . Amongst these numerous techniques of dye removal, photocatalytic degradation (one kind of Advanced Oxidation Processes AOPs) is a procedure of choice for the removal of organic compounds from wastewater, and so, a useful tool for protecting the environment 14 .…”

Experimental design methodology was applied for the optimization of indigo carmine dye photocatalytic degradation by supported TiO 2 and UV light in a flow reactor. The variables considered were the initial concentration, pH, volume of solution and recirculation flow rate. The effects of individual variables and their interaction effects for the photocatalytic degradation efficiency (%) were determined. From statistical analysis, the most effective parameters were pH and initial concentration. The optimized condition of the photocatalytic degradation of indigo carmine were; initial concentration, 4 mg L -1 ; pH, 3; volume of solution, 2540 mL; recirculation flow rate, 400 mL min -1 .

“…Ancak pH>pH pzc olduğunda hidroksiapatitin yüzeyi de negatif yüklendiğinden yüksek pH değerlerinde boya giderimi azalmaktadır. Benzer eğilim anyonik boya olan kongo kırmızısı ve dispers mavi boyalarının sırasıyla hidroksiapatit/kitosan ve hidroksiapatit ile giderimlerinde de gözlenmiş olup, bu çalışmalarda da pH 4-8 aralığında birbirine yakın giderimler elde edilirken, pH 8'den boyaların giderim verimleri düşmüştür [18,19].…”

ÖZBu 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.Anahtar Kelimeler: Adsorpsiyon, alizarin kırmızı boyası, anyonik boya, hidroksiapatit, renk giderimi REMOVAL OF ALIZARIN RED DYE USING HYDROXYAPATITE BY ADSORPTION PROCESS ABSTRACTIn 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.
