Issue 3 of Photochemical & Photobiological Sciences is now available to read online.
The front cover this month feature work by Halan Prakash and colleagues from the Birla Institute of Technology and Science, India, who looked at the ability of persulphate to cause degradation of organic contaminants and also its effect on bacteria in aqueous media. The team used methyl orange, a model azo dye, and Gram positive and negative bacteria. Visible light activation of persulphate was achieved using ruthenium(II) polypyridyl complexes, which produced sulphate radicals and led to significant degradation of methyl orange as well as complete inactivation of bacteria.
