Abstract: 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.

Key words: glyphosate, glycine, adsorption, alkalescent fiber FFA-1, D301 resin
