Adsorption of Glyphosate, 2 [(Phosphonomethyl) Amino] Acetic Acid onto Activate Carbon: An Ftir-Gcms Approach in Qualitative Analysis

Year: 2026

Type: article

Abstract: The adsorption of pollutant, an orgarno-phosphorus herbicide with the general name; glyphosate, trade name; Roundup and chemically called 2-[(phosphonomethyl) amino] acetic acid or N-(phosphonomethyl) glycine was qualitatively investigated. A batch adsorption method was utilized in interacting herbicide solution with coconut shell activated carbon (CSAC). Results obtained from FTIR and GCMS revealed the adsorption of certain functional groups from the herbicide viz; Amine (peak range of 3300-3500 cm from the common surfactant, polyoxyethyleneaminein glyphosate herbicides), Carbonyl groups (1642.41 cm' peak region), Hydroxyl-groups (3200-3600 cm peak 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.
