ClearInsights into adsorption behavior and mechanism of Cu(II) onto biodegradable and conventional microplastics: Effect of aging process and environmental factors
Researchers compared how biodegradable and conventional microplastics adsorb copper ions from water, examining how aging processes and environmental factors influence this interaction.

Enhanced copper adsorption by polyamide and polylactic acid microplastics: The role of biofilm development and chemical aging
Researchers studied how chemical aging and biofilm growth on polyamide and polylactic acid microplastics changed their ability to absorb copper from water. Both processes significantly increased the surface area and chemical reactivity of the plastics, making them absorb substantially more copper than fresh microplastics. The study suggests that as microplastics age and develop biofilms in natural waterways, they become increasingly effective at concentrating heavy metals, potentially altering how these contaminants move through aquatic environments.
