Using alkalescent functional fiber FFA-1 and resin D301 as adsorbent, some effective components in wastewater from glyphosate production such as glyphosate and glycine were recovered by process of dynamic adsorption-desorption. The dynamic adsorption conditions were optimized. 4 g alkalescent fiber FFA-1, 6 g D301-C and 4 g activated carbon were packed and filled in a column, and FFA-1 column was at the bottom and D301-C column was at the top. Height/diameter ratio of both columns was 6. 25. The wastewater of 200 g was pumped continuously into FFA-1 column and temperature was controlled at the range of 30℃ to 35℃. The wastewater flow rate was 1. 6 ml · min-1 for FFA-1 column and 1. 3 ml · min-1 for D301-C column respectively. The recovery efficiencies of glyphosate and glycine were 95% and 92% respectively, and the color of wastewater was from yellow to colorless. 1.0 mol · L-1 NaOH solution was used as a desorption solvent, and the desorption rates of glyphosate and glycine were 98% and 94%, respectively. The experimental results showed that alkalescent fiber FFA-1 and D301 resin had higher regeneration ability.
