Valorization of Tunisian silica sand for the synthesis of silica gel and its application as a sustainable adsorbent for crystal violet dye removal

Key Points

• Silica gel synthesized from Tunisian silica sand removes crystal violet dye effectively, achieving significant adsorption.
• Key metrics reveal over 90% dye removal efficiency in controlled tests with silica gel under specific conditions.
• Assessment using chemical synthesis techniques identifies optimal conditions for silica gel formation and dye adsorption.
• Highlights the potential of using local silica resources for sustainable environmental applications and waste management.
