SUMMARY OF RESEARCH WORK DONE SO FAR Research work leading to Ph.D was carried by me at the Punjabi University, Patiala, Punjab, India with Prof. A.L.J. Rao. During this work we developed different spectrophotometric methods for the determination of several metal ions and pesticides via complexation with suitable organic reagents for the colour development. Polarographic studies of the pesticides and metal ions were also carried out and these were applied for their analysis in several commercial samples, synthetic mixtures and residue analysis.
