摘要:Waste water generated from dyeing unit is highly coloured and exerts high SOD, COD, turbidity, etc. Low cost adsorbent for the treatment of waste water can make the treatment process more economical, variation in the pollution load make the treatment more difficult since most of the dyeing units are located in small scale sector. The object of this work is to determine adsorption behavior of a low cost adsorbent for the adsorption of Dyes - Methylene blue and Congo Red. The experiment was carried out at the temperature 25°CS2•C (Constant temperature) and hence adsorption Isotherms are helpful in determining the various parameters known as-well-as unknown. The values form Langmuir Isotherm for CR and MB are R2 - 0.9269 and0.9382, QM - 0.150 and 0.8851,KL - 50393 and 0.263 respectively. And the Values from Frenudlich Isotherm for MB and CR are R2 - 0.9354 and 0.9952, Kf -6394.5 and 93084, n - 0.1948 and 058018 respectively. From this result It is clear that for this experiment Freundlich isotherm is best fitted. This result shows that the experiment was successfully performed.
