Brazilian researchers develop method of purifying water contaminated by glyphosate
Publicado em 22 setembro 2023
The technique uses functionalized cellulose fibers from sugarcane bagasse to remove residues of the herbicide from an aqueous medium
Researchers at São Paulo State University (UNESP) in Brazil have developed a strategy for removing glyphosate, one of the world’s most frequently used herbicides, from water. Inspired by the concept of the circular economy, the technique is based on sugarcane bagasse, a waste material produced by sugar and ethanol plants.

Scientists develop method to produce hydrogen peroxide without emitting CO2; process synthesizes peroxide from oxygen using carbon nitride photocatalysis, which potentially could be activated with sunlight instead of artificial lighting: study
Publicado em 31 janeiro 2023Hydrogen peroxide is used to sterilize medical equipment, to bleach fabric, pulp and paper, and whiten teeth, among other applications A study published in ACS Applied Materials & Interfaces, a journal of the American Chemical Society, describes a novel method of producing hydrogen peroxide (H2O2) without emitting carbon dioxide (CO2), one of the main greenhouse gases and one of the world's most widely produced chemicals. Hydrogen peroxide is used to bleach fabric, pulp and paper, [...]ver notícia
