STUDY OF Cr(VI) PHOTOREDUCTION CATALYZED BY CDO-ZEOLITE [PDF]

Indonesian Journal of Chemistry, 2010
An attempt to decrease Cr(VI) ions in the solution which is more toxic than Cr(III) has performed by assisting the photoreduction of Cr(VI) ions catalysed by oxide Cd(II) supported in the zeolite pores (CdO-zeolite). The research consists of preparation,
