Enhanced Absorption and Fluorescence quenching methods for the quantitative analysis of Cr(VI) ions using avocado seed-derived carbon quantum dots as pseudo-derivatising reagents.

AMAmahle MkhizeXNXolani NocandaIBIrvin Noel Booysen

Key Points

  • The central aim is to develop efficient methods for the quantitative analysis of Cr(VI) ions using carbon quantum dots.
  • Developed absorption and fluorescence quenching techniques.
  • Utilized carbon quantum dots derived from avocado seeds as pseudo-derivatising reagents.
  • Conducted quantitative analyses in controlled water samples.
  • Achieved selective and ultra-sensitive detection of Cr(VI) ions.
  • Demonstrated rapid and low-cost analytical capabilities for water testing.

Abstract

Water pollution by chromate emissions or leachates, especially from ferrochrome mining and the downstream processing industries, is prevalent and pervasive, and requires selective, ultra-sensitive, rapid, and low-cost methods for routine...
