ACS Sustainable Chemistry & Engineering, Journal Year: 2022, Volume and Issue: 10(37), P. 12433 - 12447

Published: Sept. 7, 2022

Plastic and biomass waste pose a serious environmental risk; thus, herein, we mixed with plastic bottle (PET) to produce char composite materials for producing magnetic better separation when used in water treatment applications. This study also calculated the life cycle impacts of preparation adsorbent material 11 different indicator categories. For 1 functional unit (1 kg pomace leaves as feedstock), abiotic depletion fossil fuels global warming potential were quantified 7.17 MJ 0.63 CO2 equiv production materials. The (MPBC) was then remove crystal violet dye from its aqueous solution under various operational parameters. kinetics isotherm statistical theories showed that sorption CV onto MPBC governed by pseudo-second-order, Langmuir models, respectively. quantitative assessment capacity clarifies produced exhibited an admirable ability 256.41 mg g-1. Meanwhile, recyclability 92.4% demonstrated after 5 adsorption/desorption cycles. Findings this will inspire more sustainable cost-effective sorbents, including those derived combined streams.
