Isotherm Study of Methyl Orange Dye Adsorption

Water pollution is caused by a number of pollutants, such as natural resource extraction, oil pollution, agricultural practices, nuclear waste spillage, and industrial waste. One such industry is the textile industry that utilises a great deal of water and synthetic dyes that can cause harmful effect to living organism. In order to save human life and aquatic eco system, adsorption is the most efficient technique used for treatment of wastewater containing dyes. The aim of this research is to study the adsorption isotherm of MO dye on the adsorption process using the low rank coal (LRC) as adsorbents. Different amount of adsorbent (60 - 140 mg) was placed in contact with the dye's solution in the required contact time (5 - 60 min). After the adsorption process was ended, the shaker was turned off and the remained MO dyes concentration was measured using UV-Vis spectrophotometer. The adsorption isotherm of MO dye solution well fit to Freundlich adsorption isotherm
