Hem farmasötik endüstrisinin atık suları hem de evsel kullanım sonucu doğadaki su ortamlarına karışan biyomoleküllerden biri olan nikotinik asitin sulardan arıtılması insan ve çevre sağlığı üzerindeki olumsuz etkilerinden dolayı önem taşımaktadır. Bu sebeple bu çalışmada nikotinik asitin sulardan arıtılması maliyet ve kullanım açısından pek çok avantaj taşıyan adsorpsiyon yöntemi kullanılarak incelenmiştir. Adsorban olarak seçilen granüler ticari aktif karbonun nikotinik asiti sulu ortamdan uzaklaştırma etkinliği ve sıcaklık, pH gibi faktörlerin adsorpsiyon sürecine olan etkisi araştırılmıştır. Farklı başlangıç derişimlerindeki nikotinik asit çözeltileri kullanılarak çalkalama süresinin adsorpsiyon miktarı üzerindeki etkisi takip edilerek öncelikle adsorpsiyonun dengeye gelme süresi belirlenmiştir. Elde edilen kinetik veriler Lagergren 1. derece ve Yalancı 2. derece eşitlikleri ile modellenmiştir ve verilerin Lagergren 1. derece eşitliğine daha iyi uyduğu görülmüştür. Adsorpsiyon mekanizmasında tanecik içi difüzyonunun rol oynadığı ortaya koyulmuş ve hızı kontrol eden tek adımın tanecik içi difüzyon olmadığı anlaşılmıştır. Denge süresi boyunca yürütülen çalışmalardan elde edilen denge verileri ise Langmuir ve Freundlich izoterm eşitlikleri kullanılarak modellenmiş ve izoterm sabitleri hesaplanmıştır. Giles sınıflandırmasına göre L tipine uyduğu gözlemlenen nikotinik asit adsorpsiyonunun Langmuir denklemine daha iyi uyduğu tespit edilmiş ve adsorpsiyon kapasitesinin sıcaklığın düşmesi ile arttığı, ortamın pH değerinin değişmesinden ise önemli ölçüde etkilendiği tespit edilmiştir.

Purification of Vitamins from Waters: Nicotinic Acid Adsorption

Öz

Purification of nicotinic acid, one of the biomolecules contaminates natural waters as a result of both waste waters of pharmaceutical industry and household usage, is important due to negative effects on human and environmental health. Therefore, the removal of nicotinic acid from waters using adsorption method which has many advantages related to cost and utilization. Nicotinic acid removal performance of commercial activated carbon selected as adsorbent, and the effect of factors such as temperature, pH on the adsorption process was investigated. Time to reach equilibrium was determined initially by following up the effect of shaking time on adsorption quantity using nicotinic acid solutions having different initial concentrations. Kinetic data obtained was modeled by using Lagergren 1st order and Pseudo 2nd order equations and it was seen that experimental data better fit the Lagergren 1st order equation. It was introduced that intraparticle diffusion plays a role in the adsorption mechanism and it is understood that intraparticle diffusion is not the only step controlling the adsorption rate. Equilibrium data were modeled by using Langmuir and Freundlich equations and isotherm constants were calculated. It was determined that nicotinic acid adsorption which is L-type according to Giles classification, fits better to the Langmuir equation and the adsorption capacity increases with a decrease in the temperature while any change in the pH of the medium effects it considerably.
