Abstract

Introduction: SAWDUST as the most expensive and the most abundant adsorbent has the capacity of adsorbing heavy metals in water and wastewater. Recently, some agricultural wastes such as fern leaves, SAWDUST, wheat bran, wood, corn and so on have widely been used to remove heavy metals from aqueous solutions. SAWDUST is produced daily in industries related to wood processing. Several studies have done on the capability of SAWDUST to remove heavy metals from industrial wastewater. In this study, determination of EQUILIBRIUM TIME and major parameters of adsorption isotherms on the basic equations are considered. On one hand, adsorption isotherms were achieved by changing the mass concentration but the temperature was considered constant. On the other hand, in both methods, EQUILIBRIUM TIME was presumed stable, but the concentrations (adsorbent mass) were considered variable. Therefore, the main purpose of this study is to investigate the effects of changing mass balance of adsorbent on adsorption EQUILIBRIUM TIME. Another objective of this study is to achieve a mathematical definition for the relationship between initial concentration and ABSORPTION EFFICIENCY.
