Dye and nitro-compound pollution has become a significant issue worldwide. The adsorption degradation of dyes nitro-compounds have recently important areas study. Different methods, such as precipitation, flocculation, ultra-filtration, ion exchange, coagulation, electro-catalytic been adopted for the these organic pollutants. Apart from adsorption, photocatalytic degradation, chemical are considered most economical efficient to control water nitro-compounds. In this review, different kinds nitro-compounds, their adverse effects on aquatic organisms human beings, were summarized in depth. This review article covers comprehensive analysis over materials (porous polymer, carbon-based materials, clay-based layer double hydroxides, metal-organic frameworks, biosorbents). mechanism kinetics dye central parts structures all mentioned above discussed, along with main functional groups responsible adsorption. Removal also aim article, well used degradation. mechanisms explained comprehensively. factors highlighted. Advantages disadvantages, economic cost, discussed briefly. will be beneficial reader it aspects Future shortcomings part article. There several articles topics, but study not performed so far literature.

Abstract According to the research, zeolitic imidazolate framework (ZIF‐67) and graphene oxide (GO) nanosheets were synthesized with a guar gum (GG) biopolymer substrate form two‐component hybrid biocomposites: GO/ZIF‐67 (GOZ), GG/ZIF‐67 (GZ), three‐component GO/GG/ZIF‐67 (GGZ) polymer. These composites used adsorb malachite green (MG) cationic dye from an aqueous solution at room temperature. The chemical fractions, morphological structural properties of biocomposites determined using Fourier transform infrared spectrometer (FTIR), scanning electron microscope (SEM), X‐ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analyses. adsorption MG was carried out on polymer under different experimental conditions. high surface area GZ, GOZ, GGZ 1362.89, 754.89, 833.67 m 2 g −1 , respectively, total pore volume 0.90 cm 3 for 0.51 GOZ GGZ, respectively. removal pollutant follows pseudo‐second order model Langmuir model. mechanism involves hydrogen bonding, π‐π stacking, electrostatic interactions. showed maximum efficiency 66.6%, 74.4%, 90.1%, data show that after cycles 90%, 86%, 82%.
