“…From the SEM image, it is clearly seen that the surface of CFZ MNPs contains large grains which are agglomerated and irregular in shape. These agglomerates are formed due to the interactions between CFZ nanoparticles [23,43]. It can be also seen from the SEM image that the observed large grains are surrounded by many pores.…”

In the present study, Zn-doped cobalt ferrite (CoFe1.9Zn0.1O4) magnetic nanoparticles were successfully synthesized via sol-gel method. The prepared materials were characterized using X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The apparent density and magnetic force of CoFe1.9Zn0.1O4 nanoparticles were determined. The results revealed that the prepared materials display an adequate density and considerable magnetic force. The gravimetric oil removal capability tests were also performed to investigate the oil absorption properties of CoFe1.9Zn0.1O4 nanoparticles using four types of oil samples (crude, diesel, gasoline and hydraulic oil) as water pollutant's model. The oil removal capabilities of the prepared absorbent were found to be 13.72 ± 0.42-5.50 ± 0.53 g/g, 14.99 ± 0.95-8.86 ± 0.42 g/g, 18.23 ± 1.01-8.06 ± 1.26 g/g and 10.58 ± 0.49-5.24 ± 0.31 g/g for crude, diesel engine, gasoline engine and hydraulic oil, respectively. The results suggest that the prepared magnetic nanoparticles can be used as absorbent materials for removing oil spills from water surface.

“…(2013)]. Şekil 3.b'de krotonik asit hidrojellerinin spektrumunda 1645 ve 1520 cm -1 'deki piklerin sırasıyla -COOH grubu üzerindeki simetrik ve asimetrik C=O gerilme titreşim bantlarına karşılık geldiği düşünülmektedir [Wang, W. et al (2015)]. Şekil 3.c'de %80 krotonik asit içeren akrilamid/krotonik asit içeren hidrojeller de 1520 cm -1 'de akrilamid hidrojellerinin spektrumundan farklı olarak C=O asimetrik gerilme titreşim bandının bulunması krotonik asit moleküllerinin yapıya girdiğinin bir kanıtı olarak gösterilebilir.…”

ÖzBu çalışmada akrilamid-krotonik asit hidrojelleri metilen mavisi boyasının gideriminde adsorban olarak kullanılmıştır. Boyanın adsorpsiyonuna pH'nın, krotonik asit yüzdesinin, başlangıç boya derişiminin ve tekrar kullanım sayısının etkisi araştırılmıştır. Yalnızca akrilamidle hazırlanan hidrojellerde pH'nın artması ile adsorpsiyonda bir miktar artış görülmüştür. Akrilamid-krotonik asit hidrojellerinde pH 7, 9 ve 10'da adsorpsiyon hemen hemen yakın bulunmuş, buna karşılık pH 8'de belirgin bir azalma gözlenmiştir. Hidrojellerde bulunan krotonik asit yüzdesinin artması ile adsorpsiyon belirgin bir şekilde artmıştır. Ayrıca adsorbsiyon-desorpsiyon çalışmaları sonucu göstermektedir ki, 20 kere tekrar kullanımdan sonra bile hidrojellerin adsorpsiyon kapasitesi hemen hemen hiç azalmamıştır. Sonuçlar akrilamid-krotonik asit hidrojellerin endüstriyel ölçekte tekstil atık sularından boyaların gideriminde adsorban olarak kullanılabileceğini göstermektedir. Anahtar Kelimeler"akrilamid, krotonik asit, hidrojel, metilen mavisi, adsorpsiyon, tekstil" AbstractIn this study acrylamide-crotonic acid hydrogels are used as adsorbent for removal of methylene blue. The effects of pH, crotonic acid percentage, initial dye concentration and reusage number on the adsorption of the dye are investigated. When the pH increased adsorption also slightly increased with the hydrogels made up of only acrylamide. With the acrylamide crotonic acid hydrogels adsorption rates are similar in pH 7,9 and 10 but there is a significant decrease in pH 8. Adsorption increases with the increasing crotonic acid percentage in hydrogels. In addition, the adsorption-desorption results showed that the adsorption capacity of the hydrogel was not changed even after 20 times repeated use. Results show that acrylamide-crotonic acid hydrogels can be used as adsorbent for dye removal in industrial textile waste water.

“…Moreover, MnFe 2 O 4 provides an advantage for repeating magnetic separation with good stability. [23][24][25][26][27][28][29] It has been shown that MnFe 2 O 4 nanoparticles can be prepared via several methods such as hydrothermal, 30,31 solgel, 29,32 and co-precipitation. [33][34][35] Among these methods, coprecipitation has been widely utilized for the preparation of magnetic ferrite.…”
