Figure 7 shows the effect of activation temperature on activated carbon. The activation temperature is a very influential parameter on the pore structure of activated carbon, which determines the adsorption capacity. The variation in iodine values of activated carbon product is investigated as a function of activation temperature. TL is used as raw material and activation time is fixed at 60 min. As shown in Figure 7, the iodine value increases progressively with activation temperature, and then decreases when the temperature exceeded 600�C. At higher temperature, the pore walls between adjacent pores are probably destroyed and the micro-pores are destructed which led to the decrease in iodine value of activated carbon. Thus, it can be concluded that the optimum temperature for the production of activated carbons from TL is approximately 600�C. The adsorption experiment was carried out with, 10g/L TL for 5 to 80min at pH 6.0. The results are depicted in Figure 8. It shows that rate of RB uptake was rapid in the initial 5-30 min. which became slower during 30 to 45min and attaining equilibrium in 45 min. The percentage removal followed the same pattern and increases from 48 to 77% when time increased from 5 to 45 min. This is expected because a large number of surface sites are available for adsorption at the initial stages and after a lapse of time, the remaining surface sites are difficult to occupy because of repulsion between RB molecules of the solid and bulk phases16. Figure 9 shows the effect of pH in the range 2-10 & % dye removal. Effect of pH on the adsorption capacity of TL was studied in the pH range 2 to 10, with 50mg/L dye solution, adsorbent dose 10g/L at room temperature. % dye removal increases from 71.3 to 77.2% with increase in pH, with optimal uptake at pH 6. And further it decreases from 77.2 to 74.86%. In the pH range of 6 to 8. This trend may be explained on the basis of the fact that at pH below 6, the RB ions readily enter into the pore structure of the TL surface, whereas at pH beyond 6, the zwitter ionic form of RB in water aggregated to form a dimer, which was unable to enter into the pores. The effect of varying TL amount(2 to 30g/L) on the adsorption capacity of RB(50mg/L) is shown in Figure 10. The increase in the adsorbent amount is directly related to dye removal. The enhanced percent adsorption of RB may be due to the increased surface area and available adsorption sites with increase in TL dose. The maximum dye uptake occurred at 25g/L dose, hence, it was chosen as the optimized dose. Figure 11 shows the dye removal with particle size. The percentage of dye removal decreased from 78.1 to 70% when particle size increases from ¤75 to 250-300μm. This could be attributed to increased surface area of the smaller particles and the maximum adsorption was observed at 75μm size.
