Abstract


Spectrophotometer was used to estimate the antioxident action of Polyoxometalates (POMs;silicovanadate and iron substituted phosphotungstate) for various fixations and contrast, ascorbic acid utilization as standard.POMs have pulled in enthusiasm from an assortment of controls, and the applications in the fields of chemical investigation, catalysis, material science, atomic waste treatment, and drug are created. Three fixations were made 150 µg/ml, 100µg/ml and 50µg/ml. Antioxidant activity was measured as free radical scavenging activity by spectrophotometer.Estimated antioxidant activity of silicovanadate was as 4.5±0.763, 15±1 and 25.5±0.72 for three concentrations individually. The measured figuresof antioxidant activity of ironosubstitutedphosphotungstate were 1.2±0.529, 13±1 and 20±1 for three concentrations individually.Antioxidative action proposes its promising applications as a characteristic antioxidant cell for the treatment and counteractive action of free radicals related maladies.
