Methyl Red Dye Removal Using New Bio-Sorbents Derived From hyacinth and Tinospora Cordifolia plants From Waste Waters

Abstract

The use of eco-friendly, highly efficient, locally available, and low-cost adsorbents have been investigated for removing dyes from waste water and regarded as an ideal alternative to the current expensive methods. Adsorption of methyl red from aqueous solution using dried Hyacinth and Tinospora Cordifolia is the objective of this study. It was focusing on the effect of decolourisation due to dosage of adsorbent, initial concentration of solution, pH, contact time and the equilibrium of adsorption was modelled by different parameters. Prime pH value for dye adsorption was found to be 4.In the removal of the dye than raw bio-materials, ashes of the bio-materials are more effective. Percentage of extraction is effected in presence fivefold excess of anions. Trivalent anion, divalent, monovalent is the order of the interference. Co-cations have showed less interference. The developed methodologies are enact to industrial samples.

COMPARATIVE STUDY ON THE DISPLACEMENT OF METHYLENE BLUE FROM AQUEOUS SOLUTION USING AGRICULTURAL WASTE ACTIVATED CARBON AND ACTIVATED CARBON + Fe3O4 NANOCOMPOSITE

“…In few magnetic Nanoparticles, Fe 3 O 4 is an important one. 7,8 The different ways are used to prepare Fe3O4 Nanomaterials. Furthermore, the addition of iron oxide (Fe3O4) develops the chemical properties and recyclability of adsorbent.…”

BATCH ADSORPTION AND ISOTHERM STUDIES FOR THE REMOVAL OF MALACHITE GREEN AND REACTIVE RED 4 DYES BY USING AC-MnO2-NC PREPARED FROM Typha angustat L.

“…The rapid development of the textile industry in developing countries has triggered an increase in pollution of the aquatic environment 2 . A significant quantity of devastating water is generated having sulpHides, heavy metals, chlorine, a highly fluctuating pH salts, COD concentration ,a large number of suspended solids and temperature 3 . Many of the organic dyes are dangerous and may distress food chain and even aquatic life.…”

Adsorption Isotherm and Kinetic Studies Onto Removal of Reactive Yellow -14 Dye by Using Ixora Coccinea Leaf Powder

“…Depending on the medical condition the flower, the leaves, roots, and the stems are used to treat the various ailments in the Indian traditional system of medicine, the Ayurveda, and also in various folk medicines. Activated carbon is the most popular method used for adsorption process but the preparation of activated carbon and regeneration process are very costly.The popular techniques such as ion-exchange, Electrokinetic coagulation, electrochemical oxidation, membrane filtration, and photo-catalytic degradation process are expensive and are not applicable to large-scale treatments 12 .Hence we undertook an attempt to prepare low cost and easily available biomass material for the removal of dyes from waste water 13 .In this paper, an attempt to elucidate the potential of Ixora Coccinea leaf powder as biomass for the adsorption of Reactive Yellow dye-14 has been carried out. The effect of various parameters such as sorbent dose, contact time and pH was studied.…”
