Study on the Bioactive Properties of Polyetheretherketone

Activated carbon prepared by co-pyrolysis of waste tobacco straw and waste LDPE mulch film: characterization and application for methylene blue removal

“…[18][19][20][21] Tobacco straw was proved to be a potential raw material for preparing activated carbon. Activated carbons prepared from tobacco straw were efficient adsorbents for the removal of mercury, 22 Cr(VI), 23 Cr(III), 24 and methylene blue 21 from aqueous solutions. However, as far as we know, these studies only focus on tobacco straw, and there is no relevant research on preparing activated carbon adsorbents by mixing LDPE and tobacco straw.…”

Recycling of chromium wastes from the tanning industry to produce ceramic nanopigments

“…Trivalent chromium is much less toxic than hexavalent chromium, the latter being highly carcinogenic, as well as mutagenic. 21 However, Cr(III) can be readily converted to Cr(VI) under oxidizing conditions. According to Lindsay et al (2012), 22 the chlorination of water results in the oxidation of Cr(III) to Cr(VI) in only a few hours.…”
