  • Abstract:
  • Synthetic organic derivatives have been widely used as complexing agents for transition metal ions. Increasing use of those reagents has certainly created threat to the environment by accumulation of waste deposits in soil and water.Development of natural complexing agents has been primarily driven by a desire to minimize the use of synthetic reagents. Garcinia Indica (Kokum) fruit extract is highly selective for Cd2+ions forming coloured complex at pH 9.5. Use of Garcinia indica extract as an indicator in complexometric titrations exhibits a sharp colour change. Further, the comparative study with standard synthetic indicator also led to the conclusion that Garcinia indica as a natural complexometric indicator for Cd2+ ions imparts the same degree of precision as obtained with synthetic indicators.
