Removal Fast Green from Wastewater by Nanoparticles MCM-41 Modified with Schiff base Usig Experimental Design

Environmental pollution due to industrial effluent is a major concern because of its toxicity and threats for human beings. The environmental pollution control is one of the prime concerns of the society in today‟s context. Most of the dyes used for industrial purposes are highly toxic to aquatic life. Adsorption is an affordable and effective technique for the removal of dyes and colored pollutants from wastewater. Removal of hazardous, carcinogenic compounds from industrial wastewater is one of the growing needs in the present time. Many dyes and pigments are toxic in nature, with carcinogenic and mutagenic effects. The production of waste from many industrial processes leads to environmental pollution. Increasing use of dye in industrial processes .results in severe pollution of the environment nanoparticles MCM-41 modified with schiff base a new adsorbent is developed for efficient removal of Fast Green from Wastewater and aqueous solution. The porous NH2-MCM-41 Nano-particles formed a uniform hydrophilic and adsorptive layer on the thin-film which endowed the composite membrane with affinity Removal Fast Green from Wastewater.nanoparticle MCM-41 factionalized with Schiff base, a promising adsorbent for Imipramine removal. The modified mesoporous was characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron microscopy (SEM). The effect of various parameters on the removal efficiency of dye. The influence of variables such as pH, amount of adsorbent and sonication time on removal percentage were optimized and their main effect on removal percentage was investigated. Among various kinetic model such as pseudo first and second order, elovich and interparticle diffusion model, the pseudo second order with high correlation coefficient is applicable for explanation of experimental data. Also Isotherms studies via Langmuir adsorption, Freundlich and Temkin model show that Langmuir and Freundlich with high correlation coefficient is applicable for explanation of experimental data. A good agreement between experimental and predicted data was achieved that efficiency of this model for prediction of real optimum point. Among the well-known previously isotherm models, the experimental equilibrium data efficiently can be represented by the Langmuir model, while the rate of adsorption. Kinetic data efficiently can be interpreted by combination of pseudo-second order as well as intraparticle diffusion models. The small amount of this adsorbent (0.022 g) is applicable for removal of high amount of Fast Green (> 95%) in reasonable time (3.5 min).
