Investigating the hexavalent chromium removal from aqueous solution applying bee carcasses and corpses modified with Polyaniline

Abstract There are currently heavy metals in most industrial effluents which are among the most significant environmental pollutants. Hexavalent chromium is one of the most significant heavy metals. In this research for the first time, eliminating the hexavalent chromium from the aqueous medium/aque...

Hexavalent chromium is one of the most significant heavy metals.

The parameters effective on the adsorption process for polyethylene composite and bee carcasses and losses in the presence of polyethylene glycol suggested that the adsorption percentage increased for this composite by decreasing the pH, increasing the contact time, and increasing the adsorbent.
