Scavenging effects of L-ascorbic acid on 1,1-diphenyl-2-picrylhydrazyl in homogeneous and heterogeneous reaction systems

To obtain basic information on the effect of the dissociation of L-ascorbic acid (AsA) on its radical scavenging ability, 1,1-diphenyl-2-picrylhydrazyl (DPPH) was used in both homogeneous and heterogeneous reaction systems. In the homogeneous system, the dissociation of AsA did not affect its DPPH s...
