TL;DR: A novel adsorbent derived from grapefruit peel (GP) based biochar (GPBC) was synthesized by combined carbonization of GP and subsequent activation by GP extracts, granting GPBC-20 more abundant surface functional groups, which exerts the adsorbents superior performance for tetracycline adsorption.

TL;DR: In this article, the effect of H2O2/Fe2+ on zeta potential, particle size, morphology and texture structure of the pretreated sludge precursors and their corresponding influence on the carbonized materials were systematically evaluated.

TL;DR: In this paper, a composite polyvinylidene fluoride (PVDF) ultrafiltration membrane containing 0.1-0.6% of synthesized hydrothermal carbon nanospheres (CNS) was prepared with phase inversion method.

TL;DR: In this article, urine was used as a novel activator for sludge activation and porous carbon preparation and the influence of pyrolysis temperature in each stage and urine to sludge ratio on properties of carbon was systematically investigated by using thermogravimetric analysis, N2 adsorption-desorption technique and transmission electron microscope.

TL;DR: Sludge-derived activated carbon was prepared by Fenton activation and calcination, and used as adsorbent to eliminate Eriochrome Black T (EBT) dye from aqueous media and revealed that the adsorption of EBT onto SAC was naturally endothermic and spontaneous.
