Abstract:
Soluble substances of biological origin (SBO) isolated from urban bio-wastes (UBWs) are shown to be efficient
photosensitizers for the abatement of naphthalene sulfonates from aqueous solutions. Depletion of
70–80% of the investigated mono- and disulfonated probe substrates was demonstrated to occur after
solutions containing 20 mg L1 probe substrates in the presence of 150 mg L1 SBO were irradiated for
24 h. The residual organics in solution did not exhibit any potential acute toxicity. The photodegradation
of SBO occurred together with the photodegradation of the probe substrates. The implications of these
results for the development of products obtained from UBW are discussed. It would seem that these
bio-wastes have greater potential as a renewable, sustainable source of chemical auxiliaries than previous
studies have led us to believe.
