| Abstract Scope |
Has been investigated the efficiency of a composite material made from autoclaved cellular concrete and industrial jarosite waste in adsorbing Cr(III) from synthetic solutions. The study aimed to valorize toxic jarosite waste and provide an innovative solution for remediating waters contaminated with heavy metals. The material was prepared by mixing silica sand, cement, lime, aluminum, gypsum, and jarosite, the autoclaving at 190 °C for 12 hours. The resulting material was characterized and tested for Cr(III) adsorption capacity. Preliminary result showed that jersite-free samples achieved 64.2 % adsorption at pH 7 abd 30 °C. Adding jarosite improved adsorption, with 84.1% achieved at 0.10 % jarosite content. The study highlights the potential of this composite material for heavy metal removal from contaminated waters, with optimal conditions identified at pH 7 and 30 °C. The findings suggest a promising solution for water remediation while valorizing toxic jarosite waste. |
