Activated carbon fiber felt effectively removes the herbicide Diuron from water using a simple gravitational filtration system. This low-cost method offers a promising solution for improving drinking water quality.
Area of Science:
- Environmental Science
- Water Treatment Technologies
- Materials Science
Background:
- Diuron herbicide exposure poses risks to human health and water quality.
- Effective removal methods are needed to ensure safe drinking water.
- Activated carbon fiber felt (ACFF) is a potential adsorbent material.
Purpose of the Study:
- To evaluate the efficacy of ACFF in a gravitational filtration system for Diuron removal.
- To characterize ACFF properties relevant to contaminant adsorption.
- To identify the optimal ACFF for Diuron removal.
Main Methods:
- Gravitational filtration system utilizing ACFF on microfiltration membranes.
- Characterization of ACFF using XRD, Raman spectroscopy, N2 adsorption, ATR-FTIR, SEM, and zeta potential analysis.
- Permeation tests to assess Diuron removal efficiency and system performance.
Main Results:
- ACFF characterization indicated suitability for Diuron adsorption.
- ACFF-CO2(200)H2O demonstrated superior performance.
- The system achieved ~50% Diuron removal with high flux (>100 L/h/m²).
- The filtration system reached saturation points within 530 min (1st cycle) and 190 min (2nd cycle).
Conclusions:
- ACFF is effective for removing Diuron in a simple gravitational filtration setup.
- The ACFF-CO2(200)H2O sample showed the best results.
- This low-cost, easy-to-operate system offers a viable solution for water decontamination.
