As an eco-friendly material, Zn-adeninate bio-metal-organic framework (bio-MOF) was investigated as efficient adsorbent for both anionic and cationic dyes. The adsorption capability of the synthesized bio-MOF confirmed by its notable surface area 52.62 m2 g−1 total pore volume 0.183 cm3 g−1. profiles direct red 81 (DR-81) methylene blue (MB) dyes were under different operating parameters. optim...

Cellulose-based Ni/Cr (Ni/Cr-C) and cellulose-based Zn/Cr (Zn/Cr-C) composite materials have been successfully carried out, which is indicated by the XRD, FTIR, BET analysis. Layered double hydroxide (Ni/Cr-LDH) increased surface area from 0.128 m2/g to 2.207 in Ni/Cr-C composites, layered (Zn/Cr-LDH) also 0.133 3.714 Zn/Cr-C composites. The pHpzc of material this study pH 5.94-8.43, while opti...

In the context of circular economy, used coffee grounds were transformed into powdered activated carbon by chemical activation using potassium hydroxide. Its characterisation was conducted in comparison with that a commercial scanning electron microscopy (SEM) coupled energy dispersive X-ray microanalysis (EDX), diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Boehm titration,...

In this study, two methods were used to synthesize the NiO/C composite from agricultural waste. The mesoporous was successfully synthesized via a novel precipitation method in presence of dissolved gases. morphology composites differentiated by using characterization techniques such as X-ray diffraction, point zero charge (pHpzc), field-emission scanning electron microscopy (FESEM), Fourier tra...

Nghiên sử dụng phương pháp thường quy hiệu suất tạo than, độ tro, khối lượng riêng, pH, EC phân tích cấu trúc bằng SEM, BET, FTIR XRD. Đồng thời, hợp nitrogen thông qua phụ. Kết quả cho thấy có giữ khá l...

A comprehensive study on Phoenix dactylifera mediated green synthesis of ZnO, and different content (2%, 4%, 6%, 10%) Mn doped ZnO nanoparticles ([email protected]) were performed to evaluate the elimination dispersing acid dye methyl orange (MO) from aqueous solutions. The as-synthesized [email protected] adsorbents characterized by XRD, FT-IR, UV-VIS spectrophotometer, TEM, point zero charges...

The point of zero charge (PZC) is an inherent electrokinetic property biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report method determination PZC values ten standard BCs. We used salt addition to select BCs with suitable properties for methylene blue (MB) removal from aqueous solutions. were obtained by pyrolyzing five different biomasses at two d...

In this study, raw corn silk was considered for the removal of cadmium ions from aqueous solutions. order to improve adsorption characteristics, KOH treatment applied as a route obtain modified materials. Both materials before and after metal were characterized by pHPZC, SEM-EDX FTIR analysis. SEM images spectra revealed that alkali modification caused some structural changes could properties i...

Increasing food demand has resulted in an ever increasing for nitrogen fertilizers. Ammonium is the main constituent of these fertilizers and a threat to aquatic environments around world. With focus on treatment drinking water, scope this study was investigate influence key parameters suitability granular natural zeolites as adsorbents ammonium. Sorption experiments were performed artificial m...

A new biocomposite cross-linked glutaraldehyde-chitosan/MgO/Fe3O4 (CTS-GL/MgO/Fe3O4) adsorbent with magneto-responsiveness was prepared and applied for the removal of reactive blue 19 (RB-19), a synthetic textile dye. The CTS-GL/MgO/Fe3O4 structurally characterized using spectroscopic (XRD, FTIR, SEM–EDX), its physicochemical properties were evaluated potentiometry pHpzc analyses. influence var...
