Testing the ability to absorb the dye Reactive Red-159 of the surface was adjusted with sodium hydroxide concentration at different temperatures and 2N.1. weighing 1.75 grams of activated charcoal and baked at a temperature of 100° c for 1 hour.2. bring the prepared activated charcoal put into preparation of aqueous Reactive Red-159 200 mg/l concentrations. Test the temperature by 30, 40, and 60 degrees Celsius, respectively.3. collect samples at 0, 2, 5, 15, 25, 40, 60, 90 and 120 minutes, respectively. 4. filter the aqueous solution with a Syringe filter 0.45 PP filter, micron-sized lead solution through the filter, and then to an absorption measurements using a Spectrophotometer.5. bring up the absorption of light. Calculate the Reactive dye adsorption performance Red-159
