Study on methylene blue dye removal by eco-friendly adsorbents produced from coastal plant casuarina equaisetifolia seeds

Abstract

Water is one of the precious sources to all living things and its consumption increases as human population increases. However, water becomes polluted by anthropogenic influences in domestic, agriculture, commercial and industrial sectors especially in batik industry which consumes a large amount of water. The high color of water discharge from batik effluent can reduce the light penetration to aquatic life. Color is also most notorious characteristics of dye wastewater and has a strong negative impact to aquatic life. Methylene Blue (MB) is a common pollutant material in textile wastewater and frequently used in textile industries especially. Therefore, this study was conducted to examine the potential of C. equisetifo/ia seeds treated p-toluene sulfonic acid monohydrate as an eco-friendly adsorbent to remove the color of MB by adsorption process.
