From: The effect of pH and ionic strength on the adsorption of glyphosate onto ferrihydrite

Infrared spectra of lyophilized samples a ferrihydrite and glyphosate adsorbed onto ferrihydrite at pH 6.0, 5.0, 4.0 and 2.0 and b glyphosate The adsorption of glyphosate onto ferrihydrite was performed in NaCl solution (0.10 mol L−1)
