Present research work reports the synthesis of visible light-active ZnO photocatalyst through modification with N/GO and Fe2O3/GO. Modified samples are characterized by XRD. Photocatalytic activities measured in waste water consist organic pollutants such as Malachite green (MG). N-ZnO/GO exhibited better photocatalytic degradation compare to Fe2O3 doped ZnO. Dye follow first order kinetic rate...

Residues from the use of malachite green, a compound illegally applied as veterinary drug in aquacultures intended for human consumption, are frequently reported to occur in fish and fish products. Legally, zero tolerance applies to all residues of malachite green including its main metabolite leucomalachite green which is the dominating residue in tissues of exposed fish. In the European Union...

Abstract Heterogeneous photocatalysis is an advanced oxidation process (AOP). This technique used to degrade a wide range of pollutants in water. In this study, photocatalytic and mineralization malachite green aqueous suspension containing nickel-based catalysts copper supported on TiO 2 prepared by wet diffusional impregnation was studied using two sources irradiation: solar microwave. Photod...

Decolourization activity of Phanerochaete chrysosporium for three synthetic dyes viz., congo red, malachite green and crystal violet and impact of additional carbon and nitrogen supply on decolourization capacity of fungus were investigated. Maximum decolourizing capacity was observed up to 15 ppm. Addition of urea as nitrogen source and glucose as carbon source significantly enhanced decolouri...

The plant powder of Jaswand (Hibiscus rosa-Sinensis) were activated with sulphuric acid and used as low cost easily available and renewable biological adsorbent for the removal of acid dyes (acid blue, acid red and malachite green) from aqueous solution. Batch experiments were carried out for adsorption kinetics and isotherms. Operating variable studied were pH, temperature, adsorbent dose, ini...

We report angle-resolved second-harmonic generation (SHG) measurements from suspensions of centrosymmetric micron-size polystyrene spheres with surface-adsorbed dye (malachite green). The second-harmonic scattering profiles differ qualitatively from linear light scattering profiles of the same particles. We investigated these radiation patterns using several polarization configurations and part...

The present study evaluated the removal efficiency of two dyes, Congo red (CR) and malachite green (MG), using either fresh or dry fungal biomass species Trichoderma (T. virens T. viride) activated carbon. After 24 h, CR obtained with was higher than that For MG dye, average carbon (99%) those viride virens. Experimental results for showed a good correlation Langmuir isotherms. adsorption rates...

The zero valent iron doped polypyrrole (Ppy/Fe) was synthesized via chemical oxidative polymerization method in diethylene glycol medium for the first time this study. characterization of Ppy and Ppy/Fe composites realized by using fourier transform infrared spectrometer (FTIR), UV-visible diffuse reflectance (DRS), scanning electron microscope (SEM), elemental dispersion X-ray analysis (EDX), ...
