Abstract
Activated carbon is one of the organic materials that it’s used both in large and small industries. Activated carbon is used to remove odors, colors, tastes and other unwanted organic and inorganic impurities from domestic and industrial wastewater, air purification, food processing, and the chemical industry. The purpose of this study is to utilize reeds as raw material for activated carbon and to determine the process of making activated carbon from reesd plant with NaOH activator in order to reduce levels of chromium (Cr) using the adsorption method. This research was conducted by weighing the reeds plant then carbonated in the furnace for 1 hour with a temperature variation of 3500C, 4000C, and 4500C. After chilling the charcoal, it’s mashed using a mortar and then sieved using a 50 ± mesh sieve. Then as much as 20 grams of charcoal measuring 50 ± mesh was activated using 500 ml of NaOH solution with different concentrations of 1%; 3%; 5% by soaking for 24 hours. The carbon bath was filtered and rinsed with distilled water to neutral pH, then dried in the oven for 2 hours at 1100C. After the activation process, the activated carbon is then then applied to reduce the chromium metal content, by the adsorption method and carried out by the batch method, then the metal content after being interacted is measured byAAS.
