摘要
Treatment of colored samples with peroxide resulted in a loss of carbon-14. The proportion of counts lost varied in different biological samples even though the tracer was the same. Treatment of different amino acids with peroxide resulted in wide variations in their destruction. The results showed that the routine use of peroxide to decolorize samples may have serious drawbacks. © 1968.
