Agriculture wastes used as sorbents for dyes removal from aqueous environments

Abstract

This paper presents the preliminary experimental results of the use of some agro-industrial wastes (corncob, sunflower seed shells) as sorbents for Methylene Blue dye removal from aqueous environments. There were studied the main factors with high influence on the dye sorption process: temperature, sorbent amount, solution pH, dye concentration, and contact time. The results indicate that these materials have a good potential to remove the studied dye, and can be used as adsorbents into a treatment of industrial textile effluents before recycling or reuse, or discharging into the sewage system.
