Methyl red removal using activated carbon derived from orange peels as an adsorbent

Dye effluents are one of the major concerning problems in wastewater. The operating costs for wastewater treatment are quite high. Therefore, many researchers have identified capability of agricultural wastes as adsorbents to remove many types of pollutants including dyes. This study represents the use of orange peel in removing methyl red dyes and also makes a simple comparison between raw orange peel and activated carbon derived from orange peel. Batch adsorption study was performed to evaluate the effect of various parameters which are the effect of contact time, adsorbent dosage, size particle and pH. All the parameters were conducted at room temperature 27°C with constant shaking at 150 rpm for 80 minutes. The result shows that activated carbon derived from orange peel has the highest removal percentages of methyl red dye
which is up to 98% for 80 minutes shaking compared to raw orange peel. This study indicated that activated carbon derived from orange peel can be an attractive option in removing methyl red dye which is low cost and environmental friendly adsorbent.
