Research Paper (postgraduate) from the year 2016 in the subject Engineering - Chemical Engineering, grade: A, Andhra University (College of Engineering), course: Chemical Engineering, language: English, abstract: The aim of the present study is to optimize and model the removal of Two Azo and Two Anthra-Quinone Dyes from the dye effluent using Tunic of Allium cepa derived activated carbon using RSM. The relationship between dye removal efficiency and three main independent parameters including Temperature, Solution pH and Adsorbent Dosage were evaluated by applying central composite design (CCD) and Box–Behnken design (BBD). Water Has the high importance in industrial ad domestic areas, Where Industries consume a lot of water and releases highly toxic effluents which are really harmful to the environment containing the toxic metals like Cr, Cd, Pd, Ti, Zn and many harmful dyes etc. Textile effluent dyes are targeted I the present work which exist in two forms (i) True Color (ii) Apparent color. There are various dyes used in the textile industries among which majority of dye stuffs are majorly based on azodyes which are used to dye cotton fabric and anthra-quinone dyes. Azo Dyes: Determination of azo dyes are categorized by the presence of (-N=N-) azo group as chromophore. Azo dyes are generally found in synthetic dye classes. Previously azo dyes were applied to cotton which involves the reactions with chemical components which reacts to form the dye into the fiber or on the surface. Primuline red and Para red fall into this group of azo dyes introduces in 1880’s.Azo dyes are mostly used in cotton fabric. Anthra- quinone dyes: Determination of anthra- quinone dyes are characterized by carbonyl group (>C=O) as chromophore. Other names of anthra- quinone are anthrachinon, dioxoanthracene and different trade names like Corbit and Hoelite. The dyes like Saffranin, indigo carmine, Alizarin, Red S, Crystal violet were chosen here from the textile effluent for the removal. The source materials used here are natural powders namely Tunic of Allium cepa and its activated carbon.

Today synthetic dyes are used extensively in the textile dyeing, paper printing, color photography, pharmaceuticals, food and drink, cosmetic and leather industries. As of now, over 100,000 different dyes are available, with an annual production of over 700,000 metric tons. These industries discharge an enormous amount of colored effluents into natural water bodies, with or without treatment. The textile industry alone discharges 280,000 tons of dyes every year, making it the largest contributor to colored effluent discharge. Although a variety of treatment technologies are available, including adsorption, chemical oxidation, precipitation, coagulation, filtration electrolysis and photodegradation, biological and microbiological methods employing activated sludge, pure cultures, microbial consortia and degradative enzymes are economically viable, effective and environmentally responsible options. As such, this book gathers review articles from international experts working on the microbial degradation of synthetic dyes, offering readers the latest information on the subject. It is intended as a quick reference guide for academics, scientists and industrialists around the world.

Research Paper (postgraduate) from the year 2016 in the subject Environmental Sciences, grade: 9.00, , language: English, abstract: In this study, Taguchi L27 experimental design was utilized to optimize adsorption of Reactive Orange 12 (RO 12) dye onto magnetic manganese oxide and manganese ferrite (MO-MnF) nanocomposite. The MO-MnF nanocomposite was characterized by X-ray diffraction (XRD), scanning electron microscopic (SEM), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetometer (VSM) measurements. The experimental design was constructed with five factors (solution pH, RO 12 dye concentration, MO-MnF dose, contact time, and reaction temperature) at three different levels. The experimental conditions were optimized to maximize the RO 12 dye removal efficiency where signal-to-noise (S/N) ratio was considered as criteria. Optimum values of 2.0, 1.0 g/L, 60 min, 50 mg/L and 60°C were obtained for solution pH, MO-MnF dose, contact time, concentration of RO 12 dye, and reaction temperature, respectively for maximum RO 12 dye removal efficiency of 99.32%. This adsorption process proficiently followed pseudo-second-order and intra-particle diffusion models and exhibited applicability of Langmuir monolayer adsorption with maximum adsorption capacity of 207.90 mg/g at room temperature.

Presents recent challenges related to new forms of pollution from industries and discusses adequate state-of-the-art technologies capable to remediate such forms of pollution. Over the past few decades the boom in the industrial sector has contributed to the release in the environment of pollutants that have no regulatory status and which may have significant impact on the health of humans and animals. These pollutants also referred to as "emerging pollutants", are mostly aromatic compounds which derive from excretion of pharmaceutical, industrial effluents and municipal discharge. It is recurrent these days to find water treatment plants which no longer produce water that fits the purpose of domestic consumption based on newly established guidelines. This situation has prompted water authorities and researchers to develop tools for proper prediction and control of the dispersion of pollutants in the environment to ensure that appropriate measures are taken to prevent the occurrence of outbreaks due to sudden load of these pollutants in the water system. The chapters in this book cover a wide range of nano and bio-based techniques that have been designed for the real time detection of emerging contaminants in environmental water sources, geochemical models that are continuously improved for the prediction of inorganic contaminants migration from the mine solid wastes into ground and surface waters. Remediation strategies are also discussed and include effective techniques based on nanotechnology, advanced membrane filtration, oxidative and bio-degradation processes using various types of nanocatalysts, biocatalysts or supporting polymer matrices which are under advanced investigations for their implementation at large scale for the removal of recalcitrant pollutants from polluted water. Nano and Bio-Based Technologies for Wastewater Treatment: Prediction and Control Tools for the Dispersion of Pollutants in the Environment is divided is two sections. The first section covers the occurrence of emerging pollutants in environmental water while the second section covers state-of-the-art research on the removal of emerging pollutants from water using sustainable technologies. A total of 13 chapters addressing various topics related to the two sections are essentially based on recent developments in the respective field which could have a significant impact on the enhancement of the performance of wastewater treatment plants around the world, and especially in developing countries where access to clean and safe water remains a daily challenge.
