This article summarizes the methodology of synthesis, surface functionalization and
structural properties of rice husk-derived nanostructured carbon enterosorbents (biochars) in …

After undergoing biological treatment, wastewater still contains substances with endotoxic
activity, such as lipopolysaccharide. However, due to the increasing practice of treating …

At present, the pollution of surface water bodies by petroleum hydrocarbons occurs not only
