Pharmaceutical residue has recently been identified as environmental pollutants. A research project on detection and analysis of non-steroidal anti-inflammatory and adrenergic blocker drugs (ibuprofen, Naproxen, Diclofenac and Clofibic acid, Metoprolol, atenolol, Propranolol) in surface water is underway in our lab. The project is joined co-operation with Tennessee State University.

Mathematical correction of irrelevant absorption in spectrophotometric analysis using orthogonal polynomials has been used to develop simple stability-indicating procedures for analysis of drugs in dosage forms.
