Polyvinyl alcohol-alginate adsorbent beads for chromium (vi) removal
Chromium pollution has been an increasing concern worldwide because of its high toxicity and carcinogenic properties, and it requires an efficient purification technique. In this study, adsorbent beads containing polyvinyl alcohol (PVA) and sodium alginate were prepared by crosslinking with boric ac...

Chromium pollution has been an increasing concern worldwide because of its high toxicity and carcinogenic properties, and it requires an efficient purification technique.

Batch adsorption studies were conducted to evaluate Cr (VI) adsorption rates of PVA-alginate beads from aqueous solution under ultraviolet (UV) light illumination. The surface morphology and elemental composition of beads were examined using field emission scanning electron microscopy (FESEM) and energy dispersive spectrometer (EDS), respectively. This study revealed that the Cr (VI) adsorption rates increased remarkably with dosages of PVA and sodium alginate.
