摘要

Abstract

Removal of dye from the industrial wastewater is one of the most important subjects in water pollution regulation. Successive adsorption/desorption cycles of a basic dye

methylene blue

on the internal almond shell

sheep manure waste and sawdust were investigated using fixed bed column experiments in order to study the adsorption capacity to remove MB and adsorbent regeneration efficiency. The adsorption breakthrough curves were predicted by the Thomas model

Yoon Nelson model

and Wolborska model and modified dose-response model using non-linear regression analysis. The results showed that the modified dose-response model was more suitable for the description of breakthrough curves for three adsorbents only in the first cycle. Although sheep manure waste presents the highest adsorption capacity

it is hard to regenerate and needs more time regeneration. Conversely

the internal almond shell presents lower adsorption capacity

but they are more readily regenerated.
