“…Weber-Morris Kinetic Model: This model was preferred to examine the internal particulate diffusion phenomenon. In this model, using the formula in Equation ( 4), the effect of boundary layer resistance, balance, velocity and contact time from the parameters of solution adsorption is measured (Onursal et al, 2020).…”

In this study, the adsorption kinetics of Cu (II) and Ni (II) ions in the aqueous medium of the natural clay sample found in Kulp district of Diyarbakır province were investigated. For this purpose, the characterization of the natural clay mineral found in Kulp district of Diyarbakır province was carried out using X-Ray (XRD and XRF) and BET methods. The copper and nickel from the aqueous medium was measurmented at 25, 35 and 45 degrees. When the obtained data were applied to other models, it was found that it followed the Ho McKay equation for both ions. The qmax values here were measured as 1.51, 2.05, 2.30 for Cu (II) and 1.044, 1.086 and 1.741 for Ni (II) at the working temperatures, respectively. The increase in qmax values shows the accuracy of our study.

“…Water pollution, which is a problem all over the world, will start to decrease the amount of water due to the unconscious and irresponsible use of water and may bring water wars as an inevitable end. In this context, it has become a necessity to reduce water pollution and to raise awareness of people on this issue [1]. Among the studies on this subject, adsorption is one of the effective and cheap methods.…”

Bu çalışmada atık sulardaki ağır metallerin uzaklaştırılması için en uygun yöntemlerden biri olan adsorpsiyon yöntemi tercih edilmiş ve kadmiyumun çözeltiden giderimi için adsorban olarak Sivas Yıldızeli bölgesinden alınan kilin öğütülmesi ile elde edilen nanokil Sivas Nano Clay (SNC) kullanılmıştır. Nanokilin karakterizasyonu için; XRD, SEM-EDX, BET ve TGA analizleri yapılmıştır. Adsorplayıcının yüzey alanı 153.364 m2g-1 olarak,gözenek boyutu 3.835 nm olarak ölçülmüştür. Adsorpsiyonu etkileyen parametrelerden sıcaklık, adsorban miktarı ve hız gibi parametreler incelenmiştir. Temas süresi 180 dk olarak belirlenmiştir. Adsorpsiyon dengesi üzerine yapılan çalışmalar ise, Langmuir, Freundlich, Temkin ve Dubinin-Radushkevich izoterm modellerine uygulanmıştır. İzoterm modelleri ile ilgili yapılan regresyon sonucunda adsorpsiyonun Temkin modeline uyduğu tespit edilmiştir. Nanokilin adsorplama kapasitesi 298, 308 ve 318 K sıcaklıkları için 53.48, 49.50 ve 48.54 gmg-1 olarak belirlenmiştir. Adsorpsiyon termodinamiği çalışması ΔG° değerleri 298, 308, 318 K için sırasıyla -26.553, -27.673, -28.796 kJmol-1 ΔH° değeri 6,823 kJmol-1 ve ΔS° değeri 0.112 kJmol-1K-1 olarak bulunmuştur. ΔH°’ın pozitif değerli oluşu olayın endotermik olduğunu göstermektedir. Pozitif değer ayrıca olayın kimyasal olduğunu göstermektedir. ve ΔG°’ın negatif işarete sahip olması olayın kendiliğinden yürüdüğünü göstermektedir.
