Kinetic and Efficiency of Reactive Dye Sorption by Plant Biomass

Authors : Sunantha Laowansiri

Abstract: This research study shows the efficiency and kinetic of Reactive Red 141 (RR 141) adsorption using Cattail (CT), Water Lettuce (WL) and Activated Carbon (AC) sorbents. The sorbents were dried and sieved 100-200 mesh sizes (0.125-0.150 mm). Simulated textile wastewater 50 mL was prepared by RR 141 of 50 mg L-1 and 1,300 mg COD L-1. After that fill 1.0 g sorbents and then agitated at 130 rpm in a shaker at temperature of 25°C and adjust pH was 7±0.02 for 1440 min. Results revealed that the efficiency of RR 141 removal by CT, WL and AC were 64.84, 85.02 and 94.98%, respectively. The kinetics of RR 141 adsorption fitted for pseudo-second order. Results revealed that AC was higher and the removal of RR 141 was faster than WL and CT, respectively. However, AC gave a higher RR 141 sorption capacity than WL and CT, respectively. The qe values of CT, WL and AC were 1.63, 3.56 and 8.52 mg g-1, respectively.
