| dc.description.abstract | Effect of various adsorbents - pressmud, corncob and tea leaves on changes in colour and pH of different concentrations of three dyes at varying time interval (1, 2, 3, 4 and 5 hours) were studied. Decolourization of dye solutions increased with increasing dye concentration upto 30ppm by treatment with various adsorbents. The decolourization also increased with the increase of time up to 5 hours. However, the rate of decolourization was highest after one hour of treatment. Effects of different amounts (0.25, 0.5 and 1.0 gm/50 ml dye solution) of various adsorbents on changes in colour of three dye solutions were investigated. Decolourization was considerably increased when adsorbents were employed up to the amount of 0.5 gm; afterwards colour removal was negligible. Effects of adsorbents (pressmud, corncob and tea leaves) when employed singly and in combination, on pH, colour and COD of the dye solutions were studied. The treatment of all the dye solutions with various adsorbents, singly and in combination yield nearly the same reduction in colour and COD. | en_US |
