OPTIMIZATION OF MALACHITE GREEN DYE ADSORPTION BY CORN COB AND SAPOTA SEED

In current scenario, purification of water is a major issue facing by the entire globe and hence removal of dye from waste water has been focused extensively with an ecofriendly and cheap adsorbent. The main objective of this study to adsorb the hazardous dye Malachite Green (MG) from the aqueous solution using two plant-based waste such as corn cob and sapota seed powder by adsorption technique. This clean method was optimized using various important dye adsorption influencing factors like contact time, pH, and adsorbent dose. Both the adsorbents showed excellent ability to remove the dye (%) from aqueous medium. Among them, sapota seed exhibited better adsorption of 93.2% than corn cob of 88.1% after 30 min of incubation period using 3 g/L of adsorbent. The results found in this study depicted that theses agricultural waste will be an attractive and cost-effective candidate for removing the cationic dyes from the dye effluent.
