Abstract: The adsorption of unsuspected pollutant, an orgarno-phosphorus herbicide with the general name; glyphosate, trade name; Roundupand chemically called 2-[(phosphonomethyl) amino] acetic acid or N-(phosphonomethyl) glycine was qualitatively investigated. A batch adsorption mode was utilized as reactor in interacting herbicide solution with derived activated carbon. Results obtained from FTIR and GCMS run revealed the phenomenon likened to the adsorption of certain functional groups from the herbicide viz; NH-Amine (peak range of 3300-3500 cm-1), polyoxyethyleneaminein glyphosate herbicides,CO Carbonyl groups (3412.19cm-1 peak region), OH-groups (3200-3600 cm-1peak region) and phosphonic moiety. On comparing the original herbicide spectral with those interacted with activated carbon, the functional groups common to both had different peaks information (denoting different peak heights, intensities and types of vibrations). This is an indication that there could be possibilities of either partial adsorption as observed from band shift, band distortion and not necessarily a band disappearance as applicable to complete or total adsorption. The role played by solvent action was also discussed.
