Microplastics-biofilm interactions in biofilm-based wastewater treatment processes: A review.

Microplastics, pervasive contaminants from plastic, present significant challenges to wastewater treatment processes. This review critically examines the interactions between microplastics and biofilm-based treatment technologies, specifically focusing on the concepts of "biofilm on microplastics" and "microplastics in biofilm". It discusses the implications of these interactions in contaminant removal and process performance.

A novel approach of preparing TiO2 films at low temperature and its application in photocatalytic degradation of methyl orange.

Here we introduce a novel approach of preparing TiO(2) films on conductive substrates at low temperature by electrophoretic deposition method without successive calcinate treatment. The photocatalytic activity of the non-calcinated TiO(2) film was evaluated by degradation rate of methyl orange (MO). We found that the degradation rate of MO increased with the amount of TiO(2), and it was higher in both acidic and alkaline media than under neural condition.
