Bu çalışmada RB-5 boya maddesinin karakterize edilmesi ve kaolin üzerindeki adsorpsiyon özellikleri incelenmiştir. Adsorban, ASTM standart elekler (400 mesh) kullanılarak işlendi ve kontrollü bir laboratuvar ortamında üretildi. Prosedürün ilerlemesini ve 597 nm dalga boyunda boya absorbansını ölçmek için spektrofotometri kullandık. İncelenen ek faktörler arasında adsorban dozajı, pH, başlangıç boya konsantrasyonu ve temas süresi yer almaktadır. FTIR ve SEM analizleri, RB-5 ile adsorbe edilen kaolini tanımladı. Sonuçlar, adsorban dozajının ve alıkonma süresinin arttırılmasının, boya giderim verimliliğini önemli ölçüde arttırdığını gösterdi. Freundlich ve kısmen Langmuir izoterm modelleri, başlangıç boya konsantrasyonu için adsorpsiyon sürecini tanımlamak için kullanıldı. Adsorpsiyon kinetiği çalışmalarında modellerin kinetik çizgileri R2 değerleriyle birlikte incelendiğinde reaksiyonun ikinci dereceden olduğu belirlenmiştir. Doğal kilin RB-5 adsorpsiyonu için ΔH0, ΔG0 ve ΔS0 gibi değişkenleri bulundu. Bulgular endotermik ve kendiliğinden bir adsorpsiyon sürecine işaret etti.

Adsorption Equilibrium and Kinetic Investigations of Reactive Black 5 Dye on Kaolinite

Öz

The RB 5 dyestuff was characterized and its adsorption characteristics on kaolin were examined in this work. The adsorbent was processed using ASTM standard sieves (400 mesh) and manufactured in a controlled laboratory environment. We used spectrophotometry to measure the procedure progress and the dye absorbance at 597 nm wavelength. Additional factors that were examined included adsorbent dosage, pH, starting dye concentration, and contact time. The FTIR and SEM analyses defined the kaolin adsorbed with RB 5. The results showed that increasing the adsorbent dosage and retention duration considerably improved the dye removal efficiency. Freundlich and partly Langmuir isotherm models were used to describe the adsorption process for the initial dye concentration. It is stated that the reaction is second order when the kinetic lines of the models are examined in adsorption kinetics studies together with their R2 values. For the RB-5 adsorption of kaolin, thermodynamic variables including ΔH0, ΔG0, and ΔS0 were established. The findings pointed to an endothermic, spontaneous adsorption process.
