A novel exfoliated graphitic carbon nitride and clinoptilolite nanocomposites (Ex.g-C3N4/CP and g-C3N4/CP with a various ratios of g-C3N4 to CP) were prepared by facile method. This study evaluates the adsorption of methylene blue (MB) on the surface of synthesized adsorbents. The as-prepared composites were characterized by XRD, FT-IR, FESEM, BET and DRS. Batch experiments were carried out under various conditions, such as the amount of adsorbent and solution pH. The optimum batch experimental conditions were found under the response surface methodology. The Ex.g-C3N4/CP presented maximum removal of MB as compared to others. The removal efficiency of the as-prepared nanocomposite was significantly elevated owing to the synergistic effects. The adsorption capacities of MB (10 ppm) on Ex.g-C3N4/CP was 54.3 mg/g. The adsorption process by both composites (g-C3N4/CP and Ex.g-C3N4/CP) showed well-fitting with the Elovich kinetic model, and Langmuir isotherm. The thermodynamic study suggested that the adsorption of MB was a spontaneous and endothermic process. The reusability of g-C3N4/CP1:2 and Ex. g-C3N4/CP in removing of MB (10 ppm, pH = 9) was studied by photocatalytic regeneration under visible irradiation for three consecutive cycles. The results obtained from the experimental analyses showed that the removal of MB was easy treatment, eco-friendly, and high yield.

“…Finally, the bending vibration of water is observed at 1627 cm −1 . The sharp peak at 1013 cm −1 corresponds to Al atoms, the peaks observed in the range of 420–500 cm −1 are related to T–O 24 , 30 . The FT-IR spectra of the composites can be clearly show that peaks from 900 to 1800 cm −1 are related to C–N H–C units.…”

“…This indicates that the conversion of ZT to Fe-ZT includes at least two processes: (1) ion exchange and (2) precipitation of the Fe(III) species at the ZT surface. The conversion of ZT to Fe 3 O 4 -ZT can be performed in a water solution of FeCl 3 ·6H 2 O and FeSO 4 in a molar ratio of 2:1 under N 2 [ 17 , 46 , 47 , 48 , 49 ].…”

“…Similarly, Fe-ZT obtained from ZT from the deposit Donje Jesenje (Croatia) was found to have a specific surface area around three times larger than that of parent ZT [ 40 ]. Furthermore, a marginally greater rise in specific surface area has been noted for Fe 3 O 4 -ZT, synthesized from ZT originating from a deposit from Turkey [ 47 ].…”

Adsorptive, catalytic, and antibacterial properties of clinoptilolite-rich tuffs (ZT) are presented here. ZT transformed into Fe-containing ZT (Fe-ZT) removes various organic and inorganic anions from water. Fe-ZT, which contains selenium, is beneficial for growing Pleurotus ostreatus mushrooms. The fungi convert inorganic Se from Fe-ZT into a more useful organically bonded form. ZT and Fe-ZT as supplements retain nitrogen and potassium in sandy, silty loam and silty clay soils. ZT shows an affinity toward toxic metal cations, which are essential for cleaning contaminated water. The adsorption of atenolol, acetylsalicylic, and salicylic acid onto M-ZT (M–Cu2+, Mn2+, Ni2+, or Zn2+) from water solutions suggests that both the natures of M and pharmaceuticals have a significant impact on the adsorption mechanism and determine the adsorption capability of the ZT. ZT is an excellent carrier for ultrafine (2–5 nm) nano oxide particles, which have been shown to have catalytic activity in different chemical processes and photodegradation reactions of organic pollutants. ZT can also be transformed into SO4-SnO2-ZT, which is catalytically active as a solid acid. M-ZT is an effective carrier of valuable bacteria. Ag-ZT possesses beneficial bactericidal activity in disinfecting water and soil remediation.

Antibiyotik kalıntılarının su kaynaklarındaki toksisitesi çevreyi olumsuz etkilemektedir. Son yıllarda yapılan çalışmalar antibiyotikler gibi organik kirleticilerin ucuz ve çevreye uyumlu adsorbentlerle sulu çözeltilerden giderimine odaklanmıştır. Bu çalışmada, doğal Manisa-Gördes klinoptiloliti oksitetrasiklin hidroklorür (OTC-HCL) adsorpsiyonu, kesikli sisteminde 298-323 K'de incelenmiştir. pH, başlangıç konsantrasyonu, adsorban dozu, temas süresi, karıştırma hızı ve sıcaklığın adsorpsiyon üzerindeki etkileri incelenmiş ve optimum parametreler belirlenmiştir. Adsorpsiyon izotermleri Langmuir, Freundlich, Dubinin-Radushkevich (D-R), Temkin modelleri kullanılarak analiz edilmiştir. Kinetik sabitler yalancı birinci derece, yalancı ikinci derece, inratapartikül difüzyon ve Elovich modelleriyle belirlenmiştir. Doğal zeolitin OTC-HCL adsorpsiyonu, en iyi Freundlich izotermine ve sözde ikinci dereceden kinetik modeline uymuştur. Doğal zeolitin maksimum adsorpsiyon kapasitesi 323 K'de 60,97 mg/g olarak belirlenmiştir. Termodinamik çalışmalar, OTC-HCL’nin doğal zeolit ile adsorpsiyonunun kendiliğinden ve endotermik olduğunu göstermiştir. Doğal zeolitin fizikokimyasal karakterizasyonu adsorpsiyondan önce ve sonra, N2 adsorpsiyon-desorpsiyon, XRD, FTIR, SEM-EDX analizleri ile gerçekleştirilmiştir. Doğal zeolitin BET spesfik yüzey alanı, adsorpsiyon sürecine bağlı olarak adsorpsiyon sonrasında azalmıştır. Karakterizasyon sonuçları, doğal zeolit yüzeyinde OTC-HCL moleküllerinin başarılı bir adsorbe olduğunu göstermiştir.
