science project Adsorption of Dye by using charcoal from fruit peel waste aims to study the performance. To absorb the stain with a charcoal from waste fruit Peel. By dividing the six experimental trials is to experiment 1, study their effectiveness in absorbing the iodine solution with charcoal from discarded fruit peels. It found that the charcoal from the mangosteen is effective in absorbing the iodine solution is optimal. Two trials comparing the effectiveness in absorbing dyes with charcoal from the bark, fruit waste that sodium chloride stimulation with charcoal from. The bark, fruit waste that is not stimulated by sodium chloride. It found that coal from the fruit Peel with sodium chloride is effective in absorbing dyes better than coal from the fruit Peel is not stimulated by sodium chloride. By charcoal from mangosteen, absorb stain best. Experimental study on performance of 3 absorbs the dye mix of coal from discarded fruit peels. Each type of stimulation with sodium chloride It found that the charcoal from the mangosteen, durian, bark, mixed with charcoal from. Effective absorption of stain best. It also found that mixing the charcoal from the fruit Peel waste each type of stimulation with sodium chloride. Effective absorption of the stain is not as good as with the use of charcoal from each type of fruit Peel to absorb the stain. Four trials compared to absorb the stain with charcoal from the fruit Peel waste that stimulate with sodium chloride. By means of comparison with shake, leave It found that the process of absorbing the dye by using the method of shaking can absorb dyes better than soaking the charcoal bags unattended. Experimental study of optimum temperature at 5, which is used in the process of absorbing the dye from the bark, fruit charcoal waste that stimulate with sodium chloride. Efficiency in absorbing dyes with charcoal from the fruit Peel waste at different temperature with sodium chloride. Does not affect the absorption of the stain, and performance experiments of 6 studies to absorb the stain with charcoal from the fruit Peel waste sodium chloride stimulation compared with wood-fired? It found that coal from discarded fruit Peel that sodium chloride stimulation efficiency. To absorb the dye better than wood charcoal By charcoal from mangosteen, absorb stain best.
