The organic dyes are toxic to water, soil and plant. The conventional methods for dye effluent treatment are not able to classify the soil polluting, plant toxic and water polluting organic dyes. In this book, water polluting, soil polluting and plant toxic organic dyes are classified. The soil and plant materials are having oxygen atom in its chemical structure. The lone pair of electron present in the oxygen atom plays a chemical force to attract the cationic dyes. Hence, cationic dyes chemisorbed on soil and plant materials. Therefore cationic dyes are soil and plant toxic. The anionic dyes are repelled by the lone pair of electrons present in the oxygen atom. Hence, the anionic dyes are not able to chemisorb on soil and plant material. Then the anionic dyes are being in water and so it is water polluting. The cationic dyes chemisorbed on soil and plant are loss its chemical properties and it may biodegradable slowly. So the water polluting organic dyes directly affect the human health through drinking water. A new nano porous solid acid material is synthesised and applied to remove the organic dyes from aqueous solution. The material is green material and reusable.
