Human activities lead to the contamination of soils, natural water bodies, and, consequently, food products with various toxic compounds, including herbicides. Detonation nanodiamonds (DNDs) are promising materials for the creation of enterosorbents and purification of aquatic environments from various toxicants. The study utilized samples of diamond-containing charge (ASH-TH) and detonation nanodiamond (DND-TH), synthesized by detonating explosives (TNT – hexogen). Energy-dispersive X-ray spectroscopy, EPR spectroscopy, scanning electron microscopy, Fourier-transform IR spectroscopy, and low-temperature nitrogen adsorption were used to characterize the samples. The sorption properties of ASH-TH and DND-TH samples were studied for one of the most common and dangerous herbicides, glyphosate. Experiments were conducted in aqueous media at pH 2 and pH 8, simulating conditions in the mammalian gastrointestinal tract. It was found that the studied samples of ASH-TH and DND-TH had different sorption capacities for glyphosate, with the former exhibiting superior sorption properties. The obtained results demonstrate the potential of using detonation nanodiamonds as glyphosate adsorbents
