    Abstract: The use of unmodified and carboxymethylated granular activated carbon (GAC) for adsorption of Hg2+ and Ni2+ from aqueous solutions was assessed in this work. The effect of concentration and modification by carboxymethyl group on the adsorption of these metal ions was studied in batch process. The adsorption data were correlated with Langmuir, Freun...

    Abstract: A novel visible– light driven photocatalyst, BIMNVOX.x was synthesized by ethylene glycol–citrate sol–gel route and microwave- assisted calcination. The phocatalyst was characterized structurally by X–ray powder diffraction (XRPD) and simultaneous thermogravimetric–differential thermal analysis (TG–DTA). Its optical and surface properties were dete... Show More
