Article Synopsis
- The study investigates the conversion of palm kernel shells (PKS) into a biosorbent for removing heavy metals from wastewater, focusing on lead (Pb(II)).
- After carbonizing PKS, the biochar is chemically activated with phosphoric acid at a low temperature, which minimizes hazardous fumes compared to high-temperature methods.
- The results show effective Pb(II) removal, with a maximum adsorption capacity of 171.1 μg/g and indications that the process involves both physical and chemical adsorption mechanisms.
Article Synopsis
- Biosorption is a cost-effective and efficient technology for removing heavy metals from wastewater, specifically utilizing untreated venus shells (UVS) as a biosorbent.
- This study focused on the adsorption capabilities of UVS for copper (Cu(II)) and zinc (Zn(II)) ions in a binary solution, analyzing various factors such as initial concentration, adsorbent dosage, and particle size.
- The results showed that the pseudo-second order and intraparticle diffusion models best described the adsorption kinetics, while the Freundlich model effectively represented the equilibrium data, indicating that the adsorption mechanism involved chemisorption with competitive interactions between the two metal ions.
Photocatalytic oxidation purposes an economical and environmental friendly process to remove benzene from indoor air pollution. However, the process efficiency is primarily dependent on catalytic-film. The main purpose of this study is to synthesize pre-vulcanized latex impregnated with TiO (PVL-TiO thin film) from natural rubber to be used in photo-catalytic oxidation for benzene removal in a reactor.
