Abstract

ADSORPTION OF METHYLENE BLUE DYE FROM WASTE WATER USING TEMPLE FLORAL WASTE (AEGLE MARMELOS) LEAVES

Shilpi Shrivastava*, Dr. Sarita Shrivastava and Dr. Anand Sharma

ABSTRACT

The aim of present work was to investigate the potential of adsorption of methylene blue (MB) dye from waste water using low-cost adsorbent, Aegle marmelos leaves collected from temples of Vidisha. Batch adsorption studies were carried out and various parameters such as contact time, adsorbent dosage and initial dye concentration were studied to observe their effects in the dye adsorption process. The adsorption experiments were carried out under different conditions of initial dye concentration (25 to 200mg/L), Aegle marmelos dose (0.04-0.12)gm and contact time (10-60) min under room temperature. The optimum conditions for the adsorption of MB onto the adsorbent was found to be: contact time (60mins) for an initial MB dye concentration of 50mg/L and adsorbent dose 0.1g/100ml. The experimental equilibrium adsorption data were best fitted for both Langmuir and Freundlich models. The maximum adsorption capacities were found to be 114 mg/g and 0.5014 mg/g from the Langmuir and Freundlich models respectively. The kinetics of MB adsorption onto adsorbent was analyzed using pseudo-first-order and pseudo-second-order kinetic models. Both the kinetic models provided a good correlation for the adsorption of MB on adsorbent. The result indicated that Aegle marmelos leaves has high potential adsorption capacity for MB dye removal and waste management can also be done by using the temple floral waste as a adsorbent.

Keywords: Adsorption, Methylene blue, Aegle marmelos, Isotherms, Kinetics, Temple floral waste.
