A Study of Adsorption of Methylene Blue Using Porous Ceramic Materials

Abstract

Water pollution due to coloured effluent is a result of the production of dyes and their newlinelarge-scale use in textile and industries like paper and pulp, cosmetics, lather tanning, plastics, newlineetc. Colour in natural water is aesthetically unacceptable and might upset the biological activities newlineof the micro-organisms in the water bodies due to decrease in solar light transparency of water, newlineinfluence in photosynthesis activity and rise in chemical oxygen demand. Dyes cannot be easily newlineremoved by conventional wastewater treatment processes due to their complex structure and newlinesynthetic origin, although most dyes break down with time and exposure to sunlight, water, soap, newlineand oxidizing agents. Treatment of wastewater containing dyes has been an important and newlinechallenging area of research over the last decade newline
