Description
Summary:Some biosorbents had been used for the removal of MB from aqueous medium are listed in Table 1. [...]Bengal gram (Cicer arientinum L) is widely used in food, medicine, dye and adsorbent for the sorption of toxic contaminants as heavy metals and dyes. Heavy metal removal has also been done using modified form of this husk as an adsorbent [11]. [...]main aim of this study is to explore the binding sites of BGH by microwave activation with urea. After modification slight shifts in bands have been observed. [...]the shifts showed the formation of secondary amides on surface of BGH which favors the increase in the binding sites on the surface of adsorbent thereby making it more functional in terms of dye removal. Removal efficiency (%) of adsorbents did not change with the further increase in time, because all the active sites were occupied. [...]a contact time of 50 minutes was chosen for further study.
