"Breakthrough Method Purifies Glyphosate-Contaminated Water, Brazilian Researchers Reveal"

Originally Published 2 years ago — by Phys.org

Researchers at São Paulo State University in Brazil have developed a method for removing glyphosate, a commonly used herbicide, from water using sugarcane bagasse. The technique involves isolating and chemically functionalizing the bagasse fibers, which can then adsorb glyphosate from water through processes like filtration or centrifugation. The researchers found that the most efficient removal occurred at pH 14. Glyphosate is known to pose health risks, and its use is restricted or banned in several countries. The method developed by the Brazilian researchers offers a potential solution for purifying water contaminated with glyphosate.

Effective Techniques for Removing Glyphosate from Groundwater

Originally Published 2 years ago — by Phys.org

Researchers have developed a new class of materials called metal-organic frameworks (MOFs) that can selectively and efficiently remove the herbicide glyphosate from groundwater. MOFs are highly porous, sponge-like networks with an extremely large surface area of up to 7000 m²/g. The researchers incorporated additional pores with a diameter of up to 10 nanometers, called mesopores, into the MOFs to solve the problem of accessibility of active sites deep inside the material. The new material was able to remove three times as much glyphosate in only 20% of the time as the currently best adsorbent.
