Simultaneous Removal of 9-Aminoacridine and Orange Acridine Dyes by Mesopor MCM-41@NH2@pydc

The dye stuff lost in the textile industry poses a major problem to wastewater sources. Indeed, textile industry produces high levels of dye and floating solid materials. It is estimated that 5000 tons of dyeing materials are discharged into the environment every year. These poisonous materials absorb the oxygen of the water. This has risen much as it threatens human life and the environment. Industrial wastewaters contain various kinds of toxic substances such as cyanides, alkaline cleaning agents, degreasing solvents, oil, fat, and metals. Common ways of wastewater treatment include adsorption, sedimentation, chemical analysis, chemicoagulation, biological methods, and advanced oxidation procedures. However, these approaches are not without their disadvantages. Biological methods, for example, take much time and cannot degrade complicated dyes. Acridine and its derivatives, well known as DNA intercalates, have been widely studied from a variety of viewpoints, such as synthesis, physiochemical properties structural requirements and biological activities Acridine was first developed as dyes and during the early 20th century and its pharmacological properties were evaluated.At first mesopor MCM-41 @ NH2 @ pydc was synthesized and characterized for used as a new adsorbent to simultaneous removal of 9-aminocartidine and orange acaridine. Various techniques including fourier transform infrared spectroscopy (FT-IR(, X-Ray Diffraction (XRD), energy dispersive X-ray (EDS), Thermogravimetric Analysis (TGA) and BET were used for characterization of mesopprous. The magnetic properties of synthesized nanoparticles were investigated by vibrating sample magnetometer (VSM). This magnetic mesoporous, as a new solid phase was used for removal of 9-aminoacridine and orange acridine. The removal of this dye was determined by spectrophotometric method. The effective parameters on the removal process including, adsorbent dose, pH, contact time according to Taguchi design were investigated and optimized.The isotherm models such as Langmuir, Freundlich, and Temkin were evaluated and the equilibrium data were best described by the Langmuir model. The small amount of this adsorbent (0.06 g) is applicable for removal of high amount of 9-aminocartidine and orange acridine (> 90%) in reasonable time (30 min).
