Study on adsorption of methylene blue(MB) by sawdust
|
Abstract:
Adsorption of methylene blue(MB) by sawdust(SD) and modified sawdust(MSD) was studied in simulated wastewater.The results indicated that the maximum adsorption capacities were 29.9 mg/g and 60.6 mg/g,respectively before and after modification with initial MB concentration of 50 mg/L,pH of 6 and adsorbent concentration of 10 g/L.At the same time,the adsorption isothermal cure and kinetic equation were simulated to illustrate the adsorption effect.The isotherm indicated that the adsorption process followed the Langmuir adsorption isotherm.Kinetic studies showed that the adsorption process was found to follow pseudo-second-order kinetics equation.
