Lignocellulosic Biomass as Sorbent for Fluoride Removal in Drinking Water

Area of Science:

• Environmental Science
• Materials Science
• Public Health

Background:

• Globally, water supplies suffer from poor quality, with increasing demand and depleting sources.
• High fluoride levels (over 1.5 mg/L) in drinking water pose significant health risks, a major concern for the World Health Organization (WHO).
• Conventional water treatment methods often face challenges with cost and environmental impact.

Purpose of the Study:

• To investigate innovative and environmentally friendly materials for partial fluoride reduction in drinking water.
• To explore the potential of waste from lignocellulosic biomasses as a cost-effective alternative to commercial adsorbents.
• To address the urgent need for sustainable solutions to improve water quality and public health.

Main Methods:

• Utilizing waste derived from lignocellulosic biomasses as a basis for developing novel bioadsorbent materials.
• Evaluating the performance of these bioadsorbents in removing fluoride from water.
• Comparing the efficacy and cost-effectiveness against established inorganic-based adsorbents.

Main Results:

• Bioadsorbent materials derived from lignocellulosic biomass waste show promising performance in fluoride removal.
• These bio-based adsorbents demonstrate competitive adsorption capacities compared to conventional inorganic materials.
• Published studies indicate satisfactory results, highlighting the viability of biomass waste for water treatment.

Conclusions:

• Lignocellulosic biomass waste presents a sustainable and cost-effective resource for developing effective fluoride removal adsorbents.
• Further research is needed to optimize modification methods for enhanced adsorption capacity, selectivity, and reusability of bioadsorbents.
• Developing improved bioadsorbent technologies is crucial for ensuring access to safe drinking water globally.
