Prospective application of diethylaminoethyl cellulose (DEAE-cellulose) with a high adsorption capacity toward the detoxification of 2,4-dichlorophenoxyacetic acid (2,4-D) from water

The objective of the present study is to explore the utility of DEAE-cellulose as a prospective adsorbent towards removing 2,4-D from the water and run-off water from agricultural soils

Scholarcy highlights

  • Detoxification of pesticide residues requires effective methods
  • In order to validate the elemental composition of 2,4-D on the DEAE-cellulose, energy dispersive X-ray spectroscopy was employed, and as expected a er adsorption the presence of chlorine along with other elements were obvious in EDX spectra
  • The adsorption was very effective at neutral pH with a very high Langmuir maximum adsorption capacity of 429 mg gÀ1
  • Thermodynamic spontaneity endowed with an enthalpically favourable exothermic adsorption and fast sorption kinetics is the traits that were observed in the adsorption of 2,4-D onto the DEAE-cellulose surface
  • The adsorbent could be regenerated using acidi ed formic acid in methanol coupled with the high recovery of 2,4-D in presence of other pesticides such as 2,4-Declusturing Potential, 2,4-DB, 2,4,5-T, MCPA, MCPB, and MCPP, etc
  • The bottom line is that cellulosic adsorbent materials possess better ability to detoxify pesticide residues at ppb levels
  • Through this simple and meticulous study, DEAE-cellulose has proved to be noteworthy in the detoxi cation of 2,4-D from water
