Manufactured dyes are notably troublesome chemical toxins. The industrial wastes of these dyes are exceedingly noxious to aerobic and aquatic life and can cause compounds that show carcinogenic, mutagenic, and neurotoxic effects. In this study, cadmium imidazolate frameworks were synthesized by a solvothermal method from cadmium acetate and 2-methylimidazole in an ethanol/methanol mixture.

The results showed that the pseudo-second-kinetic model better described the adsorption kinetics of tartrazine on MoS2 and film diffusion was the rate-limiting step. In addition, the adsorption capacity of MoS2 was also performed with various organic dyes such as nile blue, janus green B, and congo red.

The materials were then characterized by SEM, BET, AFM and XRD. The produced material was used to remove methylene blue (MB) from aqueous solution by batch adsorption. Results showed that the bentonite nanoplatelets gave high adsorption ability with Langmuir maximum adsorption capacity of 312.50 mg/g, which could be a good adsorbent for removing dyes and other toxic organics in wastewater.

This study focuses on the synthesis of V-doped TiO2 materials using a modified polyol method to enhance their efficiency. The obtained materials were characterized by various methods such as XRD, EDX, FTIR, SEM, TEMSAED, Raman, and UV-Vis DRS. The results indicated the crystalline anatase phase of TiO2, with spherical morphology and an average size of 30nm. The UV-DRS measurement demonstrated that doped materials have a lower bandgap than the pristine TiO2.

In this study, we successfully synthesized a bimetallic metal-organic framework material Zn/Co-ZIF to start Peroxymonosulfate (PMS) for organic dye degradation in the water body. Material characterization was evaluated by advanced methods, such as XRD, FT-IR, SEM, EDX, and BET. The influence of different factors on methylene blue (MB) decomposition rate was investigated.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

In this study, the combination of Fe(III) and Ni(II), Cu(II), or Mn(II) metal salts bound to organic bridges were synthesized based on thermal method solvent in the presence of DMF. The structural properties of the materials were analyzed based on modern physicochemical methods (XRD, FT-IR, SEM, and BET).

Waste from Jackfruit has little economic value and often causes serious environmental problems. The conversion of jackfruit waste will help reduce waste treatment costs, provide a potential source of raw materials for the activated carbon (AC) and increase economic value. In this study, the ACs from the Jackfruit shell and pulp were synthesized by microwave assistance for removing organic dyes.
