Abstract: The removal of three dyes, methylene blue, malachite green, and rhodamine B from aqueous solutions at different concentrations, pH and temperatures by Akash Kinari coal has been studied. It has been found that per cent adsorptions of methylene blue, malachite green, and rhodamine B onto the adsorbate decrease from 97.18 to 83.90, 89.16 to 79.77 , and 78.40 to 67.35, respectively, when their concentrations in solutions are increased from 5 to 20 mg/L at 30±1 °C and at pH 6.8, 7.2 and 5.8, respectively. The rate constants of adsorption (Kad) for methylene blue, malachite green, and rhodamine B are found to vary between 4.27-3.95 x 10-2, 4.53-4.61 x 10-2 and 4.39-4.20 x 10-2 /min at 20, 30, and 40 °C, respectively. The calculated values of the Langmuir constant for adsorption capacity of the dyes (Qo) on the adsorbent at different temperatures vary from 2.12 to 1.59, 2.68 to 1.15 and 1.23 to 0.78 mg/g. There is an increase in the adsorption of methylene blue, malachite green, and rhodamine B from 74.39 to 92.80 per cent, 62.16 to 83.42 per cent, and 51.57 to 71.78 per cent, respectively (at 30±1 °C and 10 mg/L concentration) with increase in pH from 3.8 to 7.2. The adsorption of dyes, however, decreases beyond pH 7.2. Various thermodynamic parameters (G °, H ° and S °) have also been calculated. The results show that Akash Kinari coal is a good adsorbent for removal of colour from textile wastewater.
