The characteristics of the activated carbon and the changes in that of the modified activated carbon were verified by SEM, EDX, XRD, XPS, BET and FT-IR analyses;·The SEM studies indicate the formation of regular structure with net thin fibrils of AC; and spherical shape and smaller than 18nm in size of porous surface created in AC-MnO2-NC. The EDX studies show the presence of the elements, Carbon, Oxygen, Sodium, Magnesium, Phosphorous, Sulphur, Chlorine, Potassium and Calcium in AC. In case of AC-MnO2-NC in addition to these elements, the capping Manganese is proved. The XRD studies indicate the formation of short range crystalline structure and abundance of amorphous structure of the activated carbon and the modified activated carbon. The presence of Carbon and Oxygen in the activated carbon and in addition to these elements, the presence of Manganese in the modified activated carbon are also revealed by XPS studies. The BET studies show that the surface area of AC is 83.54m2/g and that for AC-MnO2-NC is 147.76m2/g. The FT-IR study suggest that the capping of MnO2 in modified activated carbon and the presence of the functional groups viz., -OH, -C=O, -C=C, -C-H, -CH2, -CH3 in the two adsorbents. The percentage of dye removal increases with increasing agitation time and adsorbent dose and decreases with increasing initial dye concentration. An increase in the time of agitation was found to be directly proportional to the amount of dye adsorbed per unit weight of the adsorbent. The adsorption of dyes from aqueous solutions attain equilibrium at different agitation time which depend on initial dye concentrations and initial pH of the dye solutions.

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.

This monograph is intended to provide a systematic presentation of theories concerning the adsorption of metal ions from aqueous solutions onto surfaces of natural and synthetic substances and to outline methods and procedures to estimate the extent and progress ofadsorption. As heavy metals and the problems associated with their transport and distribution are of serious concern to human health and the environment, the materials presented in this volume have both theoretical and practical significance. In writing this monograph, one ofour goals was to prepare a book useful to environmental workers and practicing engineers. For this reason, our presentation relies heavily on concepts commonly used in the environmental engineering literature. In fact, the volume was prepared for readers with a basic understanding of environmental engineering principles and some knowledge of adsorption processes. No prior familiarity with the ionic solute adsorption at solid-solution interfaces is assumed. Instead, introduction of the necessary background information was included. Generally speaking, metal ion adsorption may be studied in terms of three distinct but interrelated phenomena: surface ionization, complex formation, and the formation and presence of an electrostatic double layer adjacent to adsorbent surfaces. Analyses of these phenomena with various degrees of sophistication are xviii ADSORPTION OF METAL IONS FROM AQUEOUS SOLUTIONS presented, and their various combinations yield different models that describe metal ion adsorption.
